How does the chmod command affect folder permissions in PHP?

The chmod command in PHP is used to change the permissions of a file or directory. By using the chmod command, you can specify who can read, write, or execute a file or directory. This command is useful for controlling access to files and folders within your PHP application.

// Set folder permissions using chmod
$folder = 'path/to/folder';
$permissions = 0755; // Example permissions (read, write, execute for owner, read and execute for others)
chmod($folder, $permissions);
