ZWAMP Your PHP installation appears to be missing the MySQL extension which is required by WordPress

To install WordPress on the ZWAMP portable server, you need to enable the native MySQL extension in PHP. By default, only the PDY MySQL extension is enabled.

To enable the native MySQL extension in PHP, go to the folder vdrive\.sys\php\php.ini in your ZWAMP folder, and look for the following code:

;extension=php_mysql.dll

Remove the semicolon, save the file, and restart the server.
