Description:
------------
---
From manual page: http://www.php.net/function.sprintf#refsect1-function.sprintf-seealso
---

Right padding doesn't work with zeros.

Test script:
---------------
echo sprintf('%\'0-5d', 42); // output: '42   '
echo sprintf('%0-5d', 42); // output: '42   '
echo sprintf('%\'#-5d', 42); // output: '42###'

Expected result:
----------------
expected result:
echo sprintf('%\'0-5d', 42); // output: '42000'
echo sprintf('%0-5d', 42); // output: '42000'
echo sprintf('%\'#-5d', 42); // output: '42###'

The sprintf() function specified for the C standard, and upon which PHP's function is based explicitly says that "[i]f the 0 and-flags both appear, the 0 flag is ignored."

Implementing different behavior in PHP would be ill-advised.
