to PHP's relatively conservative default memory settings. In fact, there are more than 1,300 questions related to PHP memory errors on Stack Overflow alone. 98% of the time this error comes from loading more into memory than http://stackoverflow.com/questions/277224/how-do-i-catch-a-php-fatal-error what you set up PHP to handle in one process. There are other causes, but these are much less common — very rarely it can be a memory leak if you're on PHP 5.3 and above. If you aren't sure what your PHP memory limit is set to, it's helpfully included in the error message. The size is reported in bytes, though, so we've done some conversions for you: PHP: Fatal Error: Allowed http://www.airpair.com/php/fatal-error-allowed-memory-size Memory Size of 8388608 Bytes Exhausted - 8 MB PHP: Fatal Error: Allowed Memory Size of 16777216 Bytes Exhausted - 16 MB PHP: Fatal Error: Allowed Memory Size of 33554432 Bytes Exhausted - 32 MB PHP: Fatal Error: Allowed Memory Size of 67108864 Bytes Exhausted - 64 MB PHP: Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted - 128 MB PHP: Fatal Error: Allowed Memory Size of 268435456 Bytes Exhausted - 256 MB PHP: Fatal Error: Allowed Memory Size of 536870912 Bytes Exhausted - 512 MB PHP: Fatal Error: Allowed Memory Size of 1073741824 Bytes Exhausted - 1 GB 2 What do I have to do to resolve it? Your first course of action is to increase your memory limit. Note, this is a temporary debugging producedure. The goal is to increase the memory to a point where we have the application working again for the purpose of then reducing the memory usage. Once you decrease the memory usage you can lower the memory limit it to a value that's more suitable. Your plan should be to use as little memory as you could practically use where the application works and functions correctly in a production server based on the workload by your users (humans or programmatic). I usually recommend setting the memory limit to s

This function can be used for defining your own way of handling errors during runtime, for example in applications in which you need to do cleanup of data/files when a critical error happens, or when you need to trigger an error under certain conditions (using trigger_error()).
