Using the memory_limit directive
By default, a PHP script can allocate up to 128 megabytes of memory.
To change this limit, use a text editor to modify the memory_limit directive in your php.ini file. For example, to allow scripts to allocate a maximum amount of 256 megabytes of memory, use the following setting:
memory_limit = 256M
To verify the current value of the memory_limit
directive and other directives, you can use the phpinfo()
function. For more information, please see this article
