What is the impact of safe_mode configuration on PHP scripts, especially in terms of file access restrictions?

The safe_mode configuration in PHP restricts the access that PHP scripts have to files on the server. This can impact the ability of scripts to read, write, or execute files based on the permissions set by safe_mode. To ensure that your PHP scripts can still access necessary files while safe_mode is enabled, you can use the open_basedir directive to specify the directories that the script is allowed to access.

ini_set('open_basedir', '/path/to/allowed/directory');
