How to prevent a script from timing out?

[sh0wtym3]

Hey all,

 

I've created a PHP script that runs a bunch of queries, the problem is that this can take 30+ minutes.

 

I get the error "The server connection has timed out" after a while, even though I've added the following:

set_time_limit(0);

 

Is there a way to keep "refreshing" the connection, or trick the connection/browser into not timing out?
