Strip innitial zeros

[zzz]

I've got a few user IDs that have various number of characters. Currently one of my scripts allows login only when the exact digital id is entered. No, some of the users tend to add extra zeros in front (new standard) some tend to use just numbers after innitial zeros.

How can I take ids work ID whether they add zeros at the beginning or skip them at all?

Some of the IDs in the db that the script checks against have zeros and some don't...

wrote this once to strip dots and slahses from user-inputted paths. Changed not_allowed array for your needs

function clean_path($path)
  {
    $i = 0;

$not_allowed = array(
0 => "0"
);

if(in_array($path{0}, $not_allowed))
  {
  $path = substr($path, 1);
  $i = 1;
  }

  $length = strlen($path)-1;
if(in_array($path{$length}, $not_allowed)) // remove if 0-es at the end are allowed
  {
  echo 1;
  $path = substr($path, 0, $length-1);
  $i = 1;
  }

if($i == 1) 
  {
  $path = clean_path($path); 
  }

  return $path;      
 }

$id[] = '0000353';
$id[] = '7000353';
$id[] = '00003a3';
$id[] = '70003a3';
$id[] = '0000350';


function clean_id($id, $allow_trailing_zeros = true) {
	$id = (int)$id;
	if ($allow_trailing_zeros)
		return $id;
	$id = strrev($id);
	$id = strrev((int)$id);
	return $id;
}

foreach ($id as $id) {
	echo $id;
	echo '<br />';
	echo clean_id($id).'  -  '.clean_id($id, false);
	echo '<hr />';
}

like that?

Actually, you can use [man]ltrim/man to trim off leading zeros.
