RE: [PHP] Leading zeroes
Hi If it only a number in the string intval($str) should be enough to get rid of the zero unless it is only 0 Tom At 03:49 AM 24/05/2002, Liam Gibbs wrote: From version 4.1.0, $str = ltrim($str, '0') This works excellently. Thanks. One problem that I didn't think of, though: If the number is 0 (only 0), then the string ends up being empty. Is there a way around that? I put an if statement in saying if the string is empty, then the string is 0. Any better way? __ Do You Yahoo!? LAUNCH - Your Yahoo!

Depends what you mean by better, but -- in addition to the other suggestions, what about: if (strlen($str)1): $str = ltrim($str, '0'); endif; This would save doing the ltrim() on all single-character strings, but I don't know if the cost of the strlen() might offset this!

Re: [PHP] Leading zeroes
Does anybody have a clever and efficient way of getting rid of leading zeroes in a string? If the string is completely numeric, you can do something like this: $string = 005847; $string = (int)$string; Apart from that, you'll have to run it through some sort of regex, I suppose.

Re: [PHP] Leading zeroes
$str = ltrim($str,'0'); would be more efficient.

RE: [PHP] Leading zeroes
I'm a newbie, but maybe this'll do it:
if ($str!='0')
{
$str = ltrim($str, '0')
}

Duh. Sometimes I amaze myself at how stupid I can be.
Thanks. :)
