Are there best practices for troubleshooting and resolving memory-related errors in PHP?

Memory-related errors in PHP can often be resolved by increasing the memory limit in the php.ini file or within the script using the `ini_set()` function. It is also important to optimize the code to reduce memory usage, such as by using unset() to free up memory after variables are no longer needed. Additionally, using debugging tools like Xdebug can help identify memory leaks and optimize memory usage in PHP scripts.

// Increase memory limit in php.ini
ini_set('memory_limit', '256M');

// Optimize code to reduce memory usage
unset($variable);

// Use Xdebug to identify memory leaks
