How to display leading 0s

[vishalonne]

Hi Every Body

How I can add leading zeros in a number for example
if No. is 4 it should display 0004
if No. is 41 it should display 0041
if No. is 441 it should display 0441

Please give some hint.

how about trying this one
assuming $num is the number you want to fill

$num = "4";
$len = strlen($num);

$zeros = 5-$len;    
$no = "";
for($x=1;$x<=$zeros;$x++){
    $no .="0";
}
$no = $no.$num;
echo $no;

try with this

$number = 41;
printf("%04d\n", $number);

printf() in php, follows some internally implemented rules for formating the numbers based on the given expression in the left side of the statemnt as shown above

please see manual for more details about this method

let me know the status

happy coidng

to be more specific str_pad() does well for this kind of requirement

$input = "41";
echo str_pad($input, 10,"0", STR_PAD_LEFT);                  

please check this too

I use the str_pad method for this sort of thing, but can I ask why you need this? Is it necessary?
