What is the potential impact of a script trying to increase memory_limit in PHP?

Increasing the memory_limit in PHP can potentially lead to increased memory usage and may cause performance issues or even crashes if not managed properly. It is important to carefully assess the memory requirements of the script and adjust the memory_limit accordingly to ensure optimal performance without exceeding server resources.

// Increase memory_limit to 256MB
ini_set('memory_limit', '256M');
