How can the use of the ini_set function in PHP help address temporary changes needed for script execution, and what security implications should be considered?

The ini_set function in PHP can be used to temporarily change configuration settings during script execution. This can be useful for adjusting settings like memory_limit or max_execution_time for specific scripts that require more resources. However, it is important to consider the security implications of allowing script-level configuration changes, as it can potentially open up vulnerabilities if not handled carefully. 

// Increase memory limit temporarily for script execution
ini_set('memory_limit', '256M');

// Code that requires more memory goes here

// Reset memory limit back to default after script execution
ini_set('memory_limit', '-1');
