PHP Version Switcher for Apache on Windows

This script allows you to switch between different versions of PHP for your Apache server on a Windows environment. It updates the system PATH and modifies the Apache configuration to use the specified PHP version.

Supported PHP Versions

• PHP 7.4
• PHP 8.0
• PHP 8.1
• PHP 8.2
• PHP 8.3
• PHP 8.4

Prerequisites

• Apache installed and configured on your system.
• PHP versions installed in the specified directory.

Installation and Setup

1. PHP Installation:

   • Download the desired PHP versions from the official PHP website.
   • Extract each PHP version into its own directory under a common base directory. For example:

     C:/Dev/php/
     ├── php7.4/
     ├── php8.0/
     ├── php8.1/
     ├── php8.2/
     ├── php8.3/
     └── php8.4
     
     

   • Ensure that each PHP version folder contains the appropriate php.ini files and the SAPI DLL files (php7apache2_4.dll for PHP 7 and php8apache2_4.dll for PHP 8).

2. Clone the Repository or download the script file.

3. Modify the Script:

   • Open the switch-php.bat file in a text editor.
   • Update the following paths according to your installation:

   :: Define base paths for PHP installations and Apache configuration
   set "PHP_BASE_PATH=C:/Dev/php"
   set "APACHE_CONF=C:\Dev\Apache24\conf\httpd.conf"
   set "APACHE_BIN=C:\Dev\Apache24\bin\httpd.exe"

4. Ensure Apache is Running as a Service:

   • Open Command Prompt as Administrator.
   • Run the following commands to stop and start Apache as a service:

   net stop Apache2.4
   net start Apache2.4

5. Admin Privileges and Permissions:

   • Ensure you run the script as an Administrator. Right-click on Command Prompt and select "Run as administrator."
   • The script modifies system PATH and Apache configuration files, which require administrative privileges.

6. Add switch-php.bat to System PATH:

   • To easily run the script from any command prompt, you can add the directory containing switch-php.bat to your system PATH.
   • Open Command Prompt as Administrator and run the following command, replacing C:\Path\To\Script with the actual path to your script:

   setx PATH "%PATH%;C:\Path\To\Script" /M

Usage

1. Run the Script:

   • Open Command Prompt as Administrator.
   • Navigate to the directory where the script is located (or ensure it is in your PATH).
   • Run the script with the desired PHP version as an argument. For example, to switch to PHP 8.3, use:

   switch-php.bat 8.3

2. Script Output:

   • The script will update the system PATH, modify the Apache configuration, validate the configuration, and restart Apache.
   • If successful, you will see a message indicating the PHP version has been switched, and the current PHP version will be displayed.

Troubleshooting

• Ensure you run the script as an Administrator.
• Verify the paths to your PHP installations and Apache configuration.
• Check the Apache error logs if the service fails to start.
