[SOLVED] Append zeros to a number?

[Moron]

This is probably dirt simple, but I'm having a problem finding it in the manual.

 

In the database, if a number is five digits, my code echoes the entire five digits (12345), of course. If it's a single digit, I want to append four zeros to the beginning of it (00004, etc...).

 

How is this done?

 

Thanks!

I think you will need to write your own function for this.

Gimme me a minute and i will write one.

<?php
function add_zero($num)
{
if(strlen($num) != 5)
{
	$i = 0;
	$diff = 5 - strlen($num);
	while($i < $diff)
	{
		$num = 0 .$num;
		$i++;
	}
	return $num;
}
else
{
	return $num;
}
}

echo add_zero(1);
echo "<br>";
echo add_zero(204);
echo "<br>";
echo add_zero(12345);
?>

Can't you use print_r for this?

Can't you use print_r for this?

 

You meen printf?

 

printf('%05d',23);

Yep, printf...

Or you could use my solution

<?php
$number = 5;
echo str_pad($number, 5, '0', STR_PAD_LEFT);
?>

 

00005

printf() did the trick.

 

Thanks, everyone!
