You must uncomment extension_dir param line and set it to absolute path to the PHP extensions directory.

I know this is a while ago but I encountered this and followed the other answers here but to no avail, I found the solution via this question (Stackoverflow Question)

Essentially just needed to edit the php.ini file (mine was found at c:\xampp\php\php.ini) and uncomment these lines...

;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_pdo_mysql.dll

After restarting apache all was working as expected.

1. Find out which php.ini is used.

   extension="C:\php\ext\php_mysqli.dll"
   

4. Restart apache
