I want to display it without zero values, how I can do this? I do this

$pos = strpos($route, '0');
$length = count(str_split($route));
$a = $length - $pos;
$a = substr($route, 0, $a);

but it remove 3 in the end of string. Can somebody help me?

here's a nice algo:

<?php

$string = "14522354265300000000000";
$new_string = '';
for($i=0; $i<strlen($string) ; $i++){
    if($string[$i] != '0'){
        $new_string .= $string[$i];
    }
}

echo $new_string;

?>

rtrim is only if you have zero's at end of string :)
