What is the recommended best practice for adjusting the memory_limit in PHP?

When dealing with memory limit issues in PHP, it is recommended to adjust the memory_limit directive in the php.ini file. This directive controls the maximum amount of memory that a PHP script is allowed to allocate. Increasing the memory_limit can help prevent memory exhaustion errors and allow scripts to handle larger data sets or perform more complex operations.

// Adjust memory_limit in PHP
ini_set('memory_limit', '256M');
