php keeps crashing

[suffeks]

hi,

i have this one loop in my code, which takes a few hours to finish, just that alone. basically php crashes somewhere in the middle. how can i go about preventing this. i only think this happens because it might be running out of memory. i only see two solutions:

1) allocate more memory
2) somehow break loop and continue where it left off.

any help would be appreciated, thanks.

could you post the code for the loop?

basically, its like this:

for($currentpage=0; $currentpage<$maxpage; $currentpage++) {
.
.
.
foreach($maxpages as $maxpages2) {
	foreach($maxpages2 as $maxpages3) {
		$maxpage = $maxpages3;
	}
}
.
.
.
      foreach($threads as $threads2) {
		      foreach($threads2 as $threads3) {
.
.
.
                  foreach($results as $results2) {				      foreach($results2 as $results3) {
.
.
.
                  if () {
                  .
                 }
                 }
        }
}

basically thats the idea, i cant post details. basically it has to process information. whenever i dont have alot of it, it will complete successfully, like 1.5 hours. but once it starts getting alot of it, and starts running close to 2.5 hours it will crash php.
