Installing PHP on Windows 11 is a straightforward process. You’ll need to download PHP from the official website, extract the files, and configure your system’s environment variables. Once set up, you can verify the installation through the Command Prompt. This article will guide you through each step to ensure a smooth installation process.
How to Install PHP on Windows 11
By following the steps below, you’ll successfully have PHP up and running on your Windows 11 machine. This will allow you to run PHP scripts and develop web applications locally.
Step 1: Download PHP
Head over to the official PHP website and download the latest version of PHP for Windows.
Visit php.net and look for the downloads section. Make sure you select the appropriate version for your system—most likely the "Thread Safe" version for Windows.
Step 2: Extract the Files
Once downloaded, extract the ZIP file to a directory of your choice, such as C:php.
Choose a location that’s easy to remember. Extracting the files here will make the next steps simpler.
Step 3: Configure Environment Variables
Open the Start menu, type "Environment Variables," and select "Edit the system environment variables." Under "System Properties," click "Environment Variables."
In the Environment Variables window, find the "Path" variable under "System variables" and click "Edit." Add the path to the PHP directory you extracted earlier.
Step 4: Verify PHP Installation
Open Command Prompt (cmd) and type php -v. Press Enter.
If PHP is correctly installed, you should see the PHP version number along with other details. If not, double-check the path you added in the previous step.
Step 5: Configure PHP with Apache
If you’re using Apache as your web server, open the httpd.conf file located in the Apache directory and add the following lines at the end:
LoadModule php_module "C:/php/php8apache2_4.dll"
AddType application/x-httpd-php .php
PHPIniDir "C:/php"Restart Apache to apply the changes.
Step 6: Test PHP
Create a new file named test.php in your web server’s root directory with the following content:
Open your web browser and go to http://localhost/test.php. You should see a page with PHP information.
Once you complete these steps, PHP will be installed and ready to use on your Windows 11 machine. You can now start developing PHP applications locally.
