When I try to execute (some) queries in phpMyadmin I get this error

Fatal error: Maximum execution time of 60 seconds exceeded in C:\xampp\phpmyadmin\libraries\dbi\mysql.dbi.lib.php on line 140

because I have a very large table (over 9 millions records)

I have edited the file C:\xampp\php\php.ini

and changed the value of "max execution time" from 60 to 1000 then restarts the PHP and still have the same error.

Any solution?
