How can PHP memory limits be adjusted to optimize script performance?

To adjust PHP memory limits to optimize script performance, you can increase the memory_limit directive in your php.ini file or adjust it dynamically within your PHP script using the ini_set() function. Increasing the memory limit can help prevent out-of-memory errors and improve the performance of memory-intensive scripts.

// Increase memory limit in php.ini
// memory_limit = 128M

// Or adjust memory limit dynamically in PHP script
ini_set('memory_limit', '128M');
