Description:
------------
When i try to obtain a value withou the separator give me 
a strange result... 
 
$sfero = number_format("0.25", 2, '', ''); 
echo $sfero; 
 
it give 25 and not 025!!!!! 
 
now i must use 
 
$sfero = number_format("0.25", 2, ',', ''); 
$sfero = str_replace(",", "", $sfero); 
 
i don't know if is a bug but first,with other php version, 
the function number_format worked fine 

Reproduce code:
---------------
<?PHP
 
 for($i=1;$i<73;$i++){
 $sfero = ($i*0.25);
 $sfero = number_format($sfero, 2, '', '');
 echo $sfero."<br>";
 }
 
?>

Expected result:
----------------
000 
025 
050 
075 
100 
125 
150 
....etc 

Actual result:
--------------
 
25 
50 
75 
100 
125 
150 
....etc
