    For Windows:

    1. Download PHP:

      • Visit the official PHP website: php.net
      • Download the latest PHP version suited for Windows (Non-Thread Safe version is recommended for most users).
    2. Extract the Files:

      • Extract the downloaded ZIP file to a folder on your computer, for example, C:\php.
    3. Configure php.ini:

      • Copy php.ini-development to php.ini. This file is located in the PHP folder.
      • Open php.ini in a text editor.
      • Configure the file according to your needs. Common changes include setting extension_dir to point to the ext folder inside your PHP installation and uncommenting extensions you need.
    4. Add PHP to the Path Environment Variable:

      • Right-click on 'This PC' or 'My Computer' and select 'Properties'.
      • Go to 'Advanced system settings' and then 'Environment Variables'.
      • Under 'System Variables', find and edit the 'Path' variable to include the path to your PHP folder, e.g., C:\php.
    5. Test the Installation:

      • Open Command Prompt and type php -v. This should display the PHP version, indicating a successful installation.

    For Linux:

    1. Install PHP via Package Manager:

      • Open a terminal.
      • Use package manager commands like sudo apt-get install php (for Debian/Ubuntu) or sudo yum install php (for Fedora/CentOS).
    2. Check PHP Version:

      • After installation, you can check the PHP version by typing php -v in the terminal.
    3. Install Additional PHP Modules:

      • You can install additional PHP modules as needed, e.g., sudo apt-get install php-xml or sudo apt-get install php-mysql.

    For macOS:

    1. Using Homebrew:

      • Install Homebrew if it's not already installed (Visit brew.sh).
      • Open Terminal and run brew install php.
      • This command installs the latest PHP version.
    2. Check Installation:

      • Type php -v in the terminal to check the PHP version.
    3. Configure as Needed:

      • Similar to Windows, you can modify php.ini as per your requirements.

    Testing Your Setup:

    To test your PHP installation, you can create a simple PHP file, for example, info.php, with the following content:

    <?php
    phpinfo();
    ?>
    

    Place this file in your web server's root directory and access it via a web browser. It should display a page showing your PHP configuration.

    Note:

    • The steps may vary slightly depending on the specific version of the operating system and the PHP version.
    • For web development, you'll also need to install a web server (like Apache or Nginx) and, if working with databases, a database server (like MySQL or PostgreSQL).
