With the help of the programming language PHP, web designers can create dynamic content that communicates with databases. PHP is mostly used to create web-based software programs. You can use this tutorial to create your own PHP foundation.

Why are people learning PHP?

PHP began as a small open source project that grew in popularity as more people discovered how useful it was. In 1994, Rasmus Lerdorf released the first version of PHP.

PHP is an absolute must for students and working professionals who want to become great software engineers, especially if they work in the web development domain. I’ll go over some of the main benefits of learning PHP:

  • PHP is an abbreviation for “PHP: Hypertext Preprocessor”.
  • PHP is a server-level script language for HTML. It is also used to manage dynamic content, databases, session tracking and even build ecommerce web sites.
  • It supports many popular databases such as MySQL, PostgreSQL, Oracle, Sybase, Informix and Microsoft SQL Server.
  • PHP runs quickly, especially when compiled as a Unix Apache module. Once started, the MySQL server runs even the most complex queries with massive result sets in record time.
  • PHP supports a wide range of major protocols, including POP3, IMAP, and LDAP. PHP4 added support for Java and distributed object architectures (COM and CORBA), allowing for the first time n-tier development.
  • PHP is indulgent: The PHP programming language does its best to be as indulgent as possible.
  • The PHP syntax is the same as the C syntax.

PHP Attributes

PHP’s practical nature is enabled by five key characteristics:

  • Simplification
  • Effectiveness
  • Stability
  • Adaptability
  • Awareness

Hello World in PHP\

To get excited about PHP, let me give you a little traditional PHP Hello World program that you can try using the Demo link.

<html>
   
   <head>
      <title>Hello World</title>
   </head>
   
   <body>
      <?php echo "Hello, World!";?>
   </body>

</html>

PHP Implementations

As previously stated, PHP is one of the most widely used languages on the internet. I’ll list a few of them here:

  • PHP performs system functions, which means it can create, open, read, write, and close files on a system.
  • PHP can handle forms, which means it can collect data from files, save data in a file, email data and return data to the user.
  • PHP allows you to add, delete, and modify database elements.
  • Specify cookies and access cookie variables.
  • You can restrict users’ access to certain pages of your website using PHP.
  • It has the ability to encrypt data.

Readers

This PHP lesson is intended for PHP programmers who are unfamiliar with PHP ideas but have a basic grasp of computer programming.

Necessities

Before beginning this lesson, you should have a fundamental grasp of computer programming, the Internet, databases, and MySQL, among other things.

Fundamentals about PHP

A little open source effort at first, PHP grew as more users realized how beneficial it was. In 1994, Rasmus Lerdorf released PHP’s initial iteration.

  • PHP is an abbreviated version of “PHP: Hypertext Preprocessor”.
  • PHP is a server-side script language which is built into HTML. It is used for managing dynamic content, databases, session tracking, and even building entire e-commerce websites.
  • It supports a wide range of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix and Microsoft SQL Server.
  • PHP runs quickly, especially when compiled as an Apache module on the Unix side. Once launched, the MySQL server executes even the most complex queries with massive result sets in record time.
  • PHP runs quickly, especially when compiled as a Unix Apache module. Once started, the MySQL server executes even the most complex queries with massive result sets in record-breaking time.
  • PHP is lenient: The PHP programming language makes every effort to be as lenient as possible.
  • The PHP syntax is the same as the C syntax.

PHP’s most common applications

  • PHP performs system functions, which means it can create, open, read, write and close files on your system.
  • PHP can handle forms, ie collect data from files, store data in a file, email data, send data back to user.
  • PHP lets you add, remove, and modify database items.
  • Configure cookies and access cookie variables.
  • You can restrict user access to specific pages on your website using PHP.
  • It has the ability to encrypt the data.

PHP Attributes

The convenience of PHP is enabled through five key features:

  • Consistency
  • Reliability
  • Confidentiality
  • Adaptability
  • Awareness

PHP “Hello World” Script

Begin with simple PHP scripts to become acquainted with the language. is an important example, let’s start with a simple “Hello, world!”

As previously stated, PHP is embedded in HTML. This means that in addition to your regular HTML (or XHTML if you’re cutting-edge), you’ll have PHP statements like this.

<html>
   
   <head>
      <title>Hello World</title>
   </head>
   
   <body>
      <?php echo "Hello, World!";?>
   </body>

</html>

It will yield the following outcome:

Hello, World!

Examining the HTML output of the preceding example, you’ll notice that the PHP code is missing from the file sent from the server to your Web browser. All PHP on the Web page is processed and stripped away; the only thing returned to the client by the Web server is pure HTML output.

All PHP code must be contained within one of the three special markup tags ATE that the PHP Parser recognizes.

<?php PHP code goes here ?>

<?    PHP code goes here ?>

<script language = "php"> PHP code goes here </script>

The most common tag is? <?php…?> We’ll use the same tag in our tutorial as well.

In the next chapter, we’ll start setting up the PHP environment on your machine and then dive into almost all PHP-related concepts to familiarize you with the PHP language.
