PHP & Web Development Blogs

Welcome back! If you're new to this series have a look at Part 1 here

Today we are going to beef things up a bit and we will focus on the backend and some key CMS functionality.

It's time to get excited, this is where you'll start to see your barebones structure morph into something extraordinary!

Tired of my intro? That's ok! Let's jump into it!

Getting the DB on board

Before we delve into this, it's imperative that we take a minute and plan things out.

The database tables that are vital to any CMS are the menu, the user table, and the content table.

Our menu table will start of as follows:

CREATE TABLE 'mydbname'.'menus' ( 'ID' INT(11) NOT NULL AUTO_INCREMENT , 'menuname' VARCHAR(100) NOT NULL , 'item' VARCHAR(50) NOT NULL , 'itemlink' VARCHAR(100) NOT NULL , PRIMARY KEY ('ID')) ENGINE = MyISAM COMMENT = 'menu table';

Let's break this down a bit.

In the SQL above, we're creating a new table called menus.

Essentially our structure looks like this:

ID | Menuname | Item | Itemlink

Our ID field is our unique identifier (our PRIMARY KEY).

Tip: Remember, you can use raw SQL or a tool like PhpMyAdmin to create your db tables/execute SQL queries.

Next up is our user table.

CREATE TABLE 'mydbname'.'users' ( 'ID' INT(11) NOT NULL AUTO_INCREMENT , 'username' VARCHAR(100) NOT NULL , 'password' VARCHAR(50) NOT NULL , 'email' VARCHAR(100) NOT NULL , PRIMARY KEY ('ID')) ENGINE = MyISAM COMMENT = 'user table';

Visually represented this structure looks like this:

ID | Username | Password | Email

Our ID field is our unique identifier.

And finally, our content table modifications. You probably remember creating a rudimentary content table in Part 1 of the series.

ALTER TABLE 'mydbname'.'content' ADD content_type VARCHAR(50);

Yep, you guessed right, in the above statement we are altering our content table and adding a new field called content type.

Our new table structure now looks like this:

ID | Title | Content | Author | Content Type

Planning to Add to the Backend

Next , we're going to add a menu section, an add user section, and we'll also modify our content section.

Let's do this! reate a file called menus.php in your backend folder.

Next, code a HTML form to save your menu data.

The form needs the following fields:

Menu Name (we called this menuname in our db table).

Menu Item Name (we called this item in our db table).

Menu Link (we called this itemlink in our db table).

Try to follow Part 1 to do this on your own.

If you get a little stuck, that's ok. You can also follow the example below:

<form method="post" action="<?php $_SERVER['PHP_SELF'];?>"/>

<input type="text" name="menuname" class="mytextbox" placeholder="Menu Name" required />

<input type="text" name="item" class="mytextbox" placeholder="Item" required />

<input type="text" name="itemlink" class="mytextbox" placeholder="Item Link" required />

<input type="submit" value="Save Menu Item" name="savemenu" class="mybutton"/>

</form>
 

Notice the use of CSS classes? The gravy!

This will come in handy in our next tutorial.

Next, let's add the form processing code as we need to save these fields to the database. Remember to use the sanitization technique you learned in Part 2.

Add this above your <form> tag.

<?php

if(isset($_POST['savemenu'])){

include('../includes/conn.php');

if ($letsconnect->connect_error) {

die("Your Connection failed: " . $letsconnect->connect_error);

}else{

$menuname = $letsconnect ->real_escape_string($_POST['menuname']);

$item = $letsconnect -> real_escape_string($_POST['item']);

$itemlink = $letsconnect->real_escape_string($_POST['itemlink']);

$sql = "INSERT INTO menus(menuname,item,itemlink) VALUES ('".$menuname."', '".$item."', '".$itemlink."')";

if (mysqli_query($letsconnect, $sql)) {

echo "Your data was saved successfully!";

} else { echo "Error: " . $sql . "" . mysqli_error($letsconnect);

} $letsconnect->close();

}

}

?>

Ok phew, the menu data capturing section is done.

Let's move on to the user data capturing section, and modify the content capturing screen.

Repeat the steps above and create these two screens. Remember to keep an eye out for our database field names that we defined earlier! If you get stuck, look at the end result below:

Create adduser.php in your backend folder.

Create your data capturing form.

<form method="post" action="<?php $_SERVER['PHP_SELF'];?>"/>

<input type="text" name="username" class="mytextbox" placeholder="Username" required/>

<input type="password" name="password" class="mytextbox" placeholder="Password" required />

<input type="email" name="email" class="mytextbox" placeholder="Email" required />

<input type="submit" value="Save Menu Item" name="saveuser" class="mybutton"/>

</form>

Add your PHP processing code, remember the security!

Add this above your <form> tag.

<?php

if(isset($_POST[‘saveuser])){

include('../includes/conn.php');

if ($letsconnect->connect_error) {

die("Your Connection failed: " . $letsconnect->connect_error);

}else{

$menuname = $letsconnect -> real_escape_string($_POST[‘username']);

$item = $letsconnect -> real_escape_string($_POST[‘password']);

$itemlink = $letsconnect -> real_escape_string($_POST[‘email']);

$sql = "INSERT INTO menus(username,password,email) VALUES ('".$username."', '".$password."', '".$email."')";

if (mysqli_query($letsconnect, $sql)) {

echo "Your data was saved successfully!";

} else { echo "Error: " . $sql . "" . mysqli_error($letsconnect);

} $letsconnect->close();

}

}

?>

Please note that I will be covering Password security in the tutorials that follow.

Make sure that you are using your localhost server to complete this tutorial series. Do not publish your work until you complete this series.

Lastly, let's move to our content capturing screen which is currently found in index.php in the backend folder.

We will be changing this to a more professional dashboard in the tutorials that follow!
Our current file looks like this:

<html>

<head><title>Backend - Capture Content</title></head>

<body>

<?php

if(isset($_POST['savedata'])){

include('../includes/conn.php');

if ($letsconnect->connect_error) {

die("Your Connection failed: " . $letsconnect->connect_error);

}else{

$title = $letsconnect -> real_escape_string($_POST['title']);

$content = $letsconnect -> real_escape_string($_POST['content']);

$author = $letsconnect -> real_escape_string($_POST['author']);

$sql = "INSERT INTO content (title,content,author) VALUES ('".$title."', '".$content."', '".$author."')";

if (mysqli_query($letsconnect, $sql)) {

echo "Your data was saved successfully!";

} else { echo "Error: " . $sql . "" . mysqli_error($letsconnect);

} $letsconnect->close();

}

}

?>

<form action="<?php $_SERVER[‘PHP_SELF'];?>" method="post">

<input type="text" name="title" placeholder="Content Title here" required/>

<textarea name="content">Content Here</textarea>

<input type="text" name="author" placeholder="Author" required/>

<input type="submit" value="Save My Data" name="savedata"/>

</form>

</body>

</html>

We need to modify this slightly to include our new field, content_type.

Add the input field in your <form> above the submit button.

<input type="text" name="content_type" placeholder="Content Type" required/>;

Next, add the content_type to the sanitization lineup.

$content_type = $letsconnect->real_escape_string($_POST['content_type']);

Lastly, store this variable to the database by modifying the $sql.

$sql = "INSERT INTO content (title,content,author,content_type) VALUES ('".$title."', '".$content."', '".$author."', '".$content_type."')";

Conclusion

Chopping and changing is not always as daunting. Find a rhythm. There are many ways to make cumbersome coding a breeze and we will delve into that in the tutorials to come.

Challenge

Think of ways to test what we just did through retrieving and echoing data from the database.

PHP, by all means, is an immensely powerful language!



We may fall short of words, but there won't come any end to its qualities. The endless functionalities and possibilities of this server-side scripting language have managed to get it a strong and supportive community of PHP programmers on a global level. At present, PHP powers more than half on websites and applications on the internet.


Do you know what makes PHP so praiseworthy?



It is the simplicity, easy programming structure, and developer-friendly web functionalities that are to be credited to turn PHP into one of the top programming languages. You can create highly interactive and dynamic websites and applications with desired results by making use of PHP.



However, coding often could be a tough and tedious task to accomplish. As a solution to this, you get built-in PHP libraries that optimize the process of coding for maximum productivity.

But what are these libraries?

That's exactly what you will find out as you move ahead in this article, a list of top 12 PHP libraries capable of leading the development process in an intended manner.



So, without waiting any further, let's move ahead to learn about PHP libraries in-depth.

PChart

PChart is a PHP library assisting with the generation of text data in the form of something more appealing to the eyes and known as visual charts.



You can use this library to represent data as bar charts, pie charts, and many more different formats. The PHP script here utilizes SQL queries to put data in the impressive charts or graphs form.

Mink

Another well-known in the list of PHP libraries is Mink. It allows you to keep an eye on if a proper interaction is happening between your web apps and the browser. Eliminating the API differences between the two types of browser emulators, Mink offers an authentic testing environment for you. It also supports PHPUnit, Behat, and Symfony2.

Monolog

Monolog is a PHP logging library that helps you with saving logs to the specified locations by sending them to set files, sockets, inboxes, databases, or other web services. The use of the PSR-3 interface permits to type-hint logs in counter to your libraries that maintain optimum interoperability.

Hoa

This modular, extensible, and structured set of PHP libraries we know as Hoa establishes a link between the research and the industry.



It recommends essential paradigms, mechanisms, and algorithms for building the reliability of a site. Many PHP developers in different parts of the world use Hoa for ideal PHP development.

Guzzle

Guzzle is an HTTP client library for PHP that enables you to send HTTP requests to combine with web services.



It offers a simple interface that makes the development of query strings, POST requests, HTTP cookies, and many other attributes possible. You can also use Guzzle to send synchronous and asynchronous requests from the similar interface.

Ratchet

If your need is to develop real-time, two-directional apps between clients and servers over WebSockets, Ratchet is the PHP library you need to do it effectively.



Creating event-driven apps with Ratchet is a rapid, simple, and easy job to do!

Geocoder

Geocoder is a library to create applications that are very well geo-aware.



With Geocoder, there is an abstraction layer that helps with geocoding manipulations.



It is further split into two parts, known as HttpAdapter and Provider.

ImageWorkshop

ImageWorkshop is an open-source PHP library letting you work over the manipulation of images with layers. You can crop, resize, add watermarks, create thumbnails, and so much more. You can also enhance the images on the sites.

PhpThumb

phpThumb is the library specialized at handling the work associated with creating thumbnails with minimal coding. Accepting every image source type and image formats, it makes you do a lot ranging from rotating or cropping to watermarking or defining the image quality.

Parody

This simple library we know as Parody is used to copy classes and objects. It also provides results for method calls, acquiring properties, instantiating objects, and more. Sequential method chaining is used by Parody to produce defining class structures.

Imagine

This object-oriented PHP library is meant for working with images along with manipulating them. The often adopted operations such as resizing, cropping, and applying filters happen instantly and relatively well with Imagine.



With Imagine, you get a color class that forms the RGB values of any given color. Draw shapes like arc, ellipse, line, etc. with the features available.

PhpFastCache

PhpFastCache is an open-source PHP library that makes caching feasible. Coming as a single-file, it can be integrated within a matter of minutes.



Caching methods supported by PhpFastCache involve apc, memcache, memcached, wincache, pdo, and mpdo.


The Bottom Line




It's not about what extra difference these libraries make; it's about what significant individual contributions these libraries make for a final desired PHP app or website.



A PHP programmer, too, agrees with these libraries' benefits.



It's your time now to try and believe!

This comprehensive comparison between PHP vs Python can help you to choose the right language for web development. Now, we will compare some other elements that would give you a clear picture of both PHP vs Python.

1. Ease of Learning

Python is an easier language to learn compared to PHP. If you are a beginner, then Python is a good choice as you can learn it quickly. Python programs are shorter as well as easy to write in comparison to other languages.

PHP programming language is made for creating sophisticated web apps. It’s not a general-purpose language, and it takes time to learn it.

2. Ease of Use

Python is an open-source programming language that is versatile and portable. Python’s syntax is simple, and coding is easy to learn compared to PHP. But PHP is not just an ordinary programming language it’s used for creating dynamic web pages with HTML. This makes PHP more difficult to use than Python.

3. Community Support

Both PHP and Python provide good community support. PHP has been in the market for a long time and has a large community of developers. Therefore, you can immediately get support if you opt for PHP.

However, there are even many Python developers who constantly develop python apps. So, the community support in Python is also good. Consequently, we can’t say whether PHP or Python is better at providing community support.

4. Flexibility

Nowadays, web apps backed by Machine Learning are in high demand. Also, ML is a significant part of Python. Python provides many machine-learning libraries, such as Tensorflow, Theano, Pandas, and Scikit-learn. Additionally, these libraries are rapid, unique, & robust and work effectively with a web framework.

Nonetheless, Python programming language can be used in many other fields apart from web development. But when it comes to PHP, it’s best for web development. Therefore, we can say Python is a better choice here.

Our skilled developers delivers the most promising web development firms to make dynamic websites for your business.

5. Speed to Market

Python provides a comprehensive set of modules and third-party libraries to help developers finish the project faster. One of the popular web frameworks written in Python is Django. It utilizes the MVC pattern to allow developers to create apps fast using a significant division of concerns and reusability.

PHP also has a vast set of tools, frameworks, and libraries. Laravel is a popular PHP framework that allows the MVC pattern. Additionally, it comes with many helpful functionalities for web development, like routing, templating, authentication, and so on.

6. Web Frameworks

You get robust and well-designed web development frameworks both in PHP and Python. Most of the big businesses utilize web frameworks that PHP provides. For example, Laravel and Symfony are mature web frameworks, and a huge community supports them. So, we can say PHP makes web development easy.

Python also has many exceptional frameworks that are highly scalable, easy to use, fast and secure. It’s two most popular web frameworks are Flask and Django. If you want a shorter development period, then you can choose Django over PHP-based frameworks.

7. Library Management

Python uses Pip to handle and deal with packages. Pip ensures that Python app development is easy, rapid, and meets development needs. Python has powerful library management compared to PHP. It has a wide range of packages and tools that assist and make web app development easier. So, in terms of library management, Python clearly wins it.

8. Security

When it comes to security, most businesses prefer using Python. For instance, Django offers many pre-built security features that aid in safeguarding the apps from distinct security breaches & threats.

Apart from that, many government organizations rely on Python as their secret hacking tool. Most of the security problems are addressed by its large community support. However, PHP is less strong than Python in aspects of security.

9. Environment Management

In terms of handling environments, Python is the best programming language. It has a Virtualenv system that aids in installing different versions of the language and switching between them immediately.
PHP has no comparison with Python when it comes to handling environments. There’s an analog of PHP, VirtPHP, but it’s archived and not maintained. Therefore, most of the developers opt for Python.

10. Debugging

Python has an in-built debugger called Python Debugger or PDB. It utilizes many debugging strategies. PDB enables dynamic typing and lets developers work effortlessly without stating things at the start of a program.
PHP also comes with an XDebug package for handling bugs and error-checking the codes. But PHP development is quite slow in identifying and removing bugs. Therefore, it often experiences security issues.

The Bottom Line PHP vs Python: Which One You Choose for Web Development?

From the blog, you must have inferred that both PHP and Python are good for web development. However, there are many aspects in which Python wins over PHP. But this doesn’t mean that you only have to opt for Python. The selection of programming language majorly depends on the complexity and needs of the project.

In today's digital age, where data breaches and cyber attacks are increasingly prevalent, safeguarding sensitive information is paramount. Cryptography, the art of secure communication, plays a crucial role in ensuring data confidentiality, integrity, and authenticity. Implementing cryptography in PHP, one of the most widely used server-side scripting languages, offers a robust means to protect your data. In this guide, we'll explore how to utilize cryptography effectively in PHP to enhance the security of your applications.

Understanding Cryptography Basics

Before diving into PHP implementations, it's essential to grasp the fundamental concepts of cryptography. At its core, cryptography involves techniques for encrypting plaintext data into ciphertext to conceal its meaning from unauthorized parties. Key aspects of cryptography include:
   
. Encryption: The process of converting plaintext data into ciphertext using an algorithm and a secret key. This ciphertext can only be decrypted back to its original form using the appropriate decryption key.
   
. Decryption: The reverse process of encryption, where ciphertext is transformed back into plaintext using the decryption algorithm and the correct key.
   
. Symmetric Encryption: A type of encryption where the same key is used for both encryption and decryption. Examples include AES (Advanced Encryption Standard) and DES (Data Encryption Standard).
   
. Asymmetric Encryption: Also known as public-key cryptography, it involves a pair of keys: a public key for encryption and a private key for decryption. RSA and ECC (Elliptic Curve Cryptography) are common asymmetric encryption algorithms.

Implementing Cryptography in PHP

PHP provides robust cryptographic functions through its OpenSSL and Mcrypt extensions, allowing developers to implement various encryption techniques easily. Here's a step-by-step guide on how to perform common cryptographic operations in PHP:

1. Symmetric Encryption

<?php
$encryptionKey = openssl_random_pseudo_bytes(32);

$plaintext = "Sensitive data to encrypt";
$ciphertext = openssl_encrypt($plaintext, 'aes-256-cbc', $encryptionKey, 0, $iv);

$decryptedText = openssl_decrypt($ciphertext, 'aes-256-cbc', $encryptionKey, 0, $iv);

echo $decryptedText;
?>

2. Asymmetric Encryption

<?php
$config = array(
 "digest_alg" => "sha512",
 "private_key_bits" => 4096,
 "private_key_type" => OPENSSL_KEYTYPE_RSA,
);
$keyPair = openssl_pkey_new($config);

openssl_pkey_export($keyPair, $privateKey);
$publicKey = openssl_pkey_get_details($keyPair)["key"];

Best Practices for Cryptography in PHP

While implementing cryptography in PHP, it's essential to adhere to best practices to ensure maximum security:
   
. Use Strong Algorithms: Always use widely recognized cryptographic algorithms like AES for symmetric encryption and RSA for asymmetric encryption.
   
. Key Management: Safeguard encryption keys carefully. Utilize secure key management practices, such as storing keys in secure vaults and rotating them regularly.
   
. Data Integrity: Implement mechanisms to verify data integrity, such as HMAC (Hash-based Message Authentication Code), to detect tampering attempts.
   
. Secure Communication: When transmitting encrypted data over networks, use secure protocols like HTTPS to prevent eavesdropping and man-in-the-middle attacks.
   
. Stay Updated: Keep PHP and cryptographic libraries up to date to patch any security vulnerabilities and ensure compatibility with the latest cryptographic standards.

By following these guidelines and leveraging the cryptographic capabilities of PHP, developers can strengthen the security posture of their applications and protect sensitive data from unauthorized access. Remember, effective cryptography is not just about encryption but also encompasses key management, integrity verification, and secure communication practices. With diligence and proper implementation, PHP can be a powerful tool for building secure and resilient systems in today's digital landscape.
