爲什麼不能使用chmod()？

<?php 
// Read and write for owner, nothing for everybody else 
chmod("/somedir/somefile", 0600); 

// Read and write for owner, read for everybody else 
chmod("/somedir/somefile", 0644); 

// Everything for owner, read and execute for others 
chmod("/somedir/somefile", 0755); 

// Everything for owner, read and execute for owner's group 
chmod("/somedir/somefile", 0750); 
?>
