Download the (x64 or x86) zip from windows.php.net. Create a new folder in C:\wamp64\bin\php\ named php7.4.x . Extract the zip contents into this new folder.
: Point the installer to your current Wampserver installation directory (e.g., C:\wamp64 ).
Copy the wampserver.conf file from an existing PHP folder (like php7.3.x ) into your new php7.4.x folder.
: Right-click the downloaded file and select "Run as administrator" to ensure it has the necessary permissions to modify your Wamp directory.
While modern Wampserver installations often ship with PHP 8.x, many legacy projects still require PHP 7.4. To add this version to your environment, you can use official addons or perform a manual installation. There are two primary ways to obtain the necessary files:
the PHP 7.4 addon .exe from wampserver.aviatechno.net.
: The most reliable source for pre-configured addons is Wampserver Files and Addons , maintained by the community. You can find various PHP 7.4 versions (e.g., PHP 7.4.33 or 7.4.26) listed under the "Addons" section.
: After installation, left-click the Wamp icon in your tray, navigate to PHP > Version , and select 7.4.x . Method 2: Manual Installation (Advanced)
