Your PHP script will exit and a fatal error will be thrown if it has exhausted all the allocated memory.

PHP Fatal error: Allowed memory size of xxxx bytes exhausted (tried to allocate yyyy) in yourscript.php

This is to protect the system in the case that a rogue PHP script or application consume more memory that the system can handle.

You can fix the issue by allocating more memory to your PHP scripts and there are a few ways to do this.
