Need to copy a specific text generated on page to a string in PHP

Solution:

Try this:

<?php
function getUrlPart($url = '') {

    $urlarr = parse_url($url);
    $split = explode('/', $urlarr['path']);
    $c = 1;

    while($split[count($split)-$c] == ''){
        $c++;
    }

    return var_export($split[count($split)-$c], true);

}

$url = 'https://secure.nmi.com/api/v2/three-step/44505010//';

echo getUrlPart($url);

In this method you can get the route name at any depth, even with query parameters at the end.

Solution:

$yourUrl = 'https://secure.nmi.com/api/v2/three-step/44505010';    
$reference = (int) explode('/', $yourUrl)[6];

This assumes the general URL format does not change.
