Set maximum execution time in MYSQL / PHP

You can make it by setting set_time_limit in you php code (set to 0 for no limit)

set_time_limit(0);

Or modifying the value of max_execution_time directly in your php.ini

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

; Maximum execution time of each script, in seconds
; http://php.net/max-execution-time
; Note: This directive is hardcoded to 0 for the CLI SAPI
max_execution_time = 120  

Or changing it with ini_set()

ini_set('max_execution_time', 120); //120 seconds

but note that for this 3rd option :

max_execution_time

You can not change this setting with ini_set() when running in safe mode. The only workaround is to turn off safe mode or by changing the time limit in the php.ini.
