[SOLVED] how to get 3 digits in a for loop

[samoht]

hello all,

 

I have a simple for loop to populate a select box from 1 to 300 the only problem is the client wants the values to always have 3 digits - so 1 should be 001 and 2 should be 002 etc and 10 would be 010.

 

I don't think number_format() will help me - What can I do?

 

Thanks

while (str_length($Value) < 3)
{
$Value = "0" . $Value;
}

 

or try str_pad

for ($i = 1001; $i <= 1300; $i++) {
   $id = substr($i,-3);
}

or

for ($i = 1; $i <= 300; $i++) {
   $id = str_pad($i,3,'0',STR_PAD_LEFT);
}

function ZeroFill($number) {
if (strlen($number) == 1) {
	$number = "00".$number;
} elseif (strlen($number) == 2) {
	$number = "0".$number;
}

return $number;
}

or just do...

$number = (string)$number;

Thanks for the replies!

 

I'm not sure how to do the last suggestion but

for ($i = 1; $i <= 300; $i++) {
   $id = str_pad($i,3,'0',STR_PAD_LEFT);
}

 

is quite simple. Thanks
