I’ve tried everything to change the max_execution_time of a php crawler script so that it can run an infinite amount of time.

I have changed the php.ini file setting max_execution_time to 0 or 100000000 but with no change

I’ve also tried setting it from the php script itself by using ini_set('max_execution_time', 0);

All php scripts throw the same error Fatal error: Maximum execution time of 3000 seconds exceeded, what could I be missing and how can I make sure there is no max execution time limit?

php script

<?php
ini_set('MAX_EXECUTION_TIME', -1);
error_reporting(E_ALL);  // turn on all errors, warnings and notices for easier debugging
//ini_set('max_execution_time', 123456);
ini_set('max_input_time', -1);
ini_set('memory_limit', '512M');
set_time_limit(0);
date_default_timezone_set('Europe/London');

phpinfo()

max_execution_time  0   0
max_input_time     -1   -1

    You shouldn’t let your crawler run under apache, it’s better to run it stand-alone via cli as part of a Gearman setup.

    That way it won’t hog your web server and it can run as long as you want. You can find many bindings for Gearman that you can use, including PHP of course.
