Are there any potential security risks associated with using chmod 777 in PHP scripts?

Using chmod 777 in PHP scripts can pose a potential security risk as it grants full read, write, and execute permissions to all users, which could allow unauthorized users to modify or execute sensitive files on the server. To mitigate this risk, it is recommended to use more restrictive permissions, such as chmod 755, which grants read and execute permissions to all users, but limits write permissions to the file owner.

// Set file permissions to 755 (read and execute for all users, write for owner)
$file = '/path/to/file';
chmod($file, 0755);
