Since the output of decoct( fileperms('.') ) is of the form: 40644



It seems the previous example is wrong, instead you should understand:



To get permissions formatted as "644":

<?php

echo substr(decoct( fileperms('.') ), 2);

?>



To get permissions formatted  as "0644":

<?php

echo substr(decoct( fileperms('.') ), 1);

?>

An easy way to calculate fileperms to chmod is this:



substr(decoct(fileperms("test.html")),3);



Displays 666 or 777 (depends on chmod set).



substr(decoct(fileperms("test.html")),2);



Displays 0666 or 0777 and refers immediately to the number set with chmod();

If you only want the permissions (lowest three octal numbers) you can use a bitwise AND to mask the bits:



<?php

fileperms($file) & 511; 

?>

Do not forget: clearstatcache();

==============================

 

When ever you make a:



mkdir($dstdir, 0770 ))



or a:



chmod($dstdir, 0774 ); 



You have to call:



clearstatcache();



before you can call:



fileperms($dstdir);

On Linux (not tested on Windows), if you want a chmod-like permissions, you can use this function:



<?php

function file_perms($file, $octal = false)

{

    if(!file_exists($file)) return false;



    $perms = fileperms($file);



    $cut = $octal ? 2 : 3;



    return substr(decoct($perms), $cut);

}

?>



Using it:



$ touch foo.bar

$ chmod 0754 foo.bar

<?php

echo file_perms('foo.bar'); // prints: 754

echo file_perms('foo.bar', true); // prints 0754

?>
