Capturing Out of memory exceptions

[mrbaseball34]

I understand that this is a fatal error but is there a way to catch this exception
and do any cleanup before script execution ends?

I don't believe this is possible, no.

The only way to provide detection would be to check for it proactively, e.g. check [man]memory_get_usage/man before a memory-intensive operation, calculate an estimate of how much additional memory you'll need (don't forget to add a little padding, of course), and see if this estimate will fit in memory. If so, continue as normal. If not, don't attempt the operation (obviously).

You can get fatal errors to pass to a custom error handler, that what you're looking for?

I'm changing my answer to the same as bradgrafelman, foolish to say something contradictory to him in the first place 🙂

Thinking it out; if you're out of memory, even if you could catch the error, wouldn't you not have enough memory to handle it? I think that might be a catch-22 and the only real solution is what brad described. If you give it a shot with the custom handlers let us know the results please.
