The PHP memory_limit is the maximum amount of server memory that each PHP script is
allowed to consume.
Per the PHP documentation:
"This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly
written scripts from eating up all available memory on a server."
The default value is
128MB. Often, this is raised depending on the amount of memory needed for the web application.
When the PHP script exceeds the limit, you will receive an error similar to the following example:
Fatal error: Allowed memory size of x bytes exhausted (tried to allocate x bytes) in /example/php/script PHP Fatal error: Out of memory (allocated x) (tried to allocate x bytes) in /example/php/script
You can increase the memory_limit by editing the php.ini file. You should look for a line cthat starts with memory_limit:
memory_limit = 256M
Be aware that the server has a physical memory limit. You should optimize your code if the memory_limit parameter
is already set too high.
