How to Install PHP on Windows?

To install PHP on Windows, you first need to download the PHP installation file from the official PHP website. Choose the version that is compatible with your operating system. Once the file is downloaded, run the installation wizard and follow the on-screen instructions to complete the installation process.

During the installation, you will be prompted to choose the installation directory and configure additional settings such as enabling extensions and configuring the PHP runtime.

After the installation is complete, you will need to configure your web server to recognize PHP files. If you are using Apache, you can do this by editing the httpd.conf file and adding the following lines:

1

3

LoadModule php7_module "C:/path/to/php/php7apache2_4.dll"
AddHandler application/x-httpd-php .php
PHPIniDir "C:/path/to/php"

Finally, restart your web server to apply the changes and test whether PHP is running correctly by creating a PHP file with the following code:

1

3

<?php
phpinfo();
?>

Save the file in your web server's document root directory and access it through your web browser. If PHP is installed correctly, you should see a page displaying information about your PHP installation.
