What is the maximum size of PHP arrays and how does it relate to the memory limit set in php.ini?

The maximum size of PHP arrays is determined by the memory limit set in the php.ini configuration file. If the memory limit is too low, it can prevent large arrays from being created and may result in out-of-memory errors. To increase the maximum size of PHP arrays, you can adjust the memory_limit setting in php.ini to allocate more memory to PHP scripts.

// Increase the memory limit for PHP scripts to allow for larger arrays
ini_set('memory_limit', '256M');
