What are the potential security implications of changing file permissions for driver files in PHP?

Changing file permissions for driver files in PHP can potentially lead to security vulnerabilities. By allowing more permissive permissions, unauthorized users may gain access to sensitive information or be able to modify critical files, leading to potential exploits or system compromises. It is important to carefully consider and restrict file permissions to ensure the security of the application.

// Example of setting secure file permissions for driver files
chmod("/path/to/driver/file.php", 0600);
