umask -- Changes the current umask

Description

int umask ( [int mask] )

umask() sets PHP's umask to mask & 0777 and returns the old umask. When PHP is being used as a server module, the umask is restored when each request is finished.

umask() without arguments simply returns the current umask.

Example 1. umask() example

<?php
$old = umask(0);
chmod("/path/some_dir/some_file.txt", 0755);
umask($old);

// Checking
if ($old != umask()) {
    die('An error occured while changing back the umask');
}
?>
