This tutorial will teach you the basics of php program step-by-step. You will learn how to install PHP, write PHP scripts, and use PHP to create dynamic web pages.
Step 1: Install PHP
To install PHP, you will need to install a web server. There are many different web servers available, but some of the most popular ones include Apache and Nginx. You can also use a local development environment, such as XAMPP or MAMP, which includes a web server, PHP, and other tools that you need to develop web applications.
Once you have installed a web server, you will need to install PHP. You can download PHP from the PHP website. Once you have downloaded PHP, you will need to install it on your web server.
Instructions for installing PHP on Apache:
Download the latest version of PHP from the PHP website.
Extract the PHP archive to a directory on your web server.
Open the php.ini file in a text editor.
Find the line that says extension=php.so and uncomment it.
Save the php.ini file and restart your web server.
Instructions for installing PHP on Nginx:
Download the latest version of PHP from the PHP website.
Extract the PHP archive to a directory on your web server.
Open the nginx.conf file in a text editor.
Find the section that says http { and add the following lines to the end of the section:
location ~ \.php$ {
fastcgi_pass unix:/run/php/php8.1-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
Save the nginx.conf file and restart your web server.
Instructions for installing PHP on XAMPP:
Download the latest version of XAMPP from the Apache Friends website.

Step 2: Write PHP Scripts
Once you have installed PHP, you can start writing PHP scripts. PHP scripts are files with the .php extension. You can write php program scripts in any text editor, but it is recommended to use a code editor that is designed for PHP development.
Step 3: Use PHP to Create Dynamic Web Pages
PHP can be used to create dynamic web pages. Dynamic web pages are web pages that can change their content based on user input or other factors.
To create a dynamic web page using PHP, you will need to use PHP variables. PHP variables are used to store data.
