Wouldn't it be easier to just do this?

Code:

function leading_zeros($value, $places){
	if ( is_numeric ( $value ) )
	{
		$Type = gettype ( $value ) ;
		settype ( $value, 'string' ) ;
		while ( strlen ( $value ) &lt; $places )
		{
			$value = &quot;0{$value}&quot; ;
		}
		settype ( $value, $Type ) ;
	}
	return $value ;
}

You can even pass numerical values that aren't strings to it.<br><br>Post edited by: TheDarkestDay, at: 2007/10/14 14:13

Or even simpler.
Convert $value to string first. Add the correct amount of 0's and append $ value.

Code:


function leading_zeros($value, $length = 2)
{
	$value = (string) $value;
	
	$output  = str_repeat('0', $length - strlen($value));
	$output .= $value
    return $output;
}
