What are some potential pitfalls when setting the memory limit to -1 in PHP configuration files?

Setting the memory limit to -1 in PHP configuration files can potentially allow scripts to consume unlimited memory, leading to performance issues or crashes on the server. It is generally not recommended to set the memory limit to -1 as it can cause the server to run out of memory. To avoid this issue, it is advisable to set a reasonable memory limit that meets the requirements of your application.

// Set a specific memory limit in PHP configuration file
ini_set('memory_limit', '256M');
