Execute PHP script every X seconds?

[m002.p]

Hello everyone.

I have developed a rather complex script to query a gameserver which also makes checks on players within. However the issue I am having difficulty with is running the PHP script every X seconds.

I know of a simple way which works but doesnt seem too accurate when executing it for me.

$overall_time = 0;
while ($overall_time < 60) {  $overall_time +10= ; sleep(10);

// The script

}

So I want to ask those knowledgable coders out there the best way to run a script say every 5-10 seconds using possibly a 1 min CRON kick start?

Any help appreciated.
