What are the potential pitfalls of using open_basedir in PHP settings?

Using open_basedir in PHP settings can restrict the directories from which PHP scripts can access files. This can help improve security by limiting the potential impact of a security breach. However, it can also cause issues with legitimate file access if not configured properly, potentially leading to errors or unexpected behavior in your application. 

// Example of setting open_basedir in PHP configuration
ini_set('open_basedir', '/var/www/html:/tmp');
