How to trigger and control a timeout?

[barbapapa]

Hi,

 

is there a way to set a timeout before executing a mysql query (or something else), e.g

<?php

function timeoutfunc() { echo 'timeout triggered!'; }
...
set_code_execution_timeout('45 seconds',  timeoutfunc);

mysql_query ('long query'...);
...
?>

 

This would trigger a timeout and call timeoutfunc() if exec time of query is > 45 seconds.

Of course the function set_code_execution_timeout() doesn't exist.

 

- is there a way to do the same thing?

- maybe using exceptions?

 

Thank you.
