In some application you'll need to have zero filled values for example

Array(50,60,44,null,3); 
To this 
Array(050,060,044,000,003); 

This could be usefull for example when you test user data with database values, or to do any math calculus ... 

<?PHP 

/** 
* Return zerofilled value 
* 
* @param integer $field 
* @param integer $digits 
* @return string 
*/ 
function zerofilled($field, $digits = 3){ 
    $n = strlen($field); 
    if ($n<=$digits) { 
        for ($i = 1;$i<=($digits-$n);$n++) 
            $field = "0$field"; 
    } 
    return $field; 
} 

// sample usage 

$data = array(50,60,44,null,3); 

foreach ($data as $k=>$v) { 
    echo "result $k = ".zerofilled($v,2)."\n"; 
} 

?>
