The following program can be used to display the permissions in octal format.

<?php
$file = "test.txt";
  
//displaying permissions set for the file 
//in octal format 
echo sprintf("%o", fileperms($file))."\n";

//displaying permissions set for the file 
//in octal format - considering only last 
//four characters (removing mode file types)
echo substr(sprintf("%o", fileperms($file)), -4);
?>
