What is the significance of the "0777" parameter in the mkdir function and how does it relate to file permissions?

The "0777" parameter in the mkdir function specifies the permissions of the newly created directory. In this case, "0777" means that the directory will have read, write, and execute permissions for the owner, group, and others. This is the most permissive setting, allowing full access to the directory for all users. It is important to be cautious when setting permissions to "0777" as it can pose security risks if not used carefully. 

<?php
$dir = 'new_directory';
mkdir($dir, 0777);
?>
