Description:
------------
---
From manual page: http://www.php.net/function.mkdir#refsect1-function.mkdir-
parameters
---

It can be **very** easy to omit the leading zero in the permissions argument, 
especially if working on a command line all day where "775" for example works in 
a chmod. Although the documentation clearly states it needs a leading zero, it 
would be good if the function could detect such a trivial error that can lead to 
quite bad results. It would also help consistency between the linux command line 
and php.

Test script:
---------------
<?php

mkdir("/tmp/test", 775); // This should be recognised as 0775 are only 3 characters specified

 


Expected result:
----------------
I expect the permissions to be set as "rwxrwxr-x"

Actual result:
--------------
The permissions are actually set as "r-----r-t"
