PHP equivalent to JavaScript's string split method

Question

I'm working with this on JavaScript:

<script type="text/javascript">
    var sURL = "http://itunes.apple.com/us/app/accenture-application-for/id415321306?uo=2&mt=8&uo=2";
    splitURL = sURL.split('/');
    var appID = splitURL[splitURL.length - 1].match(/[0-9]*[0-9]/)[0];
    document.write('<br /><strong>Link Lookup:</strong> <a href="http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/wa/wsLookup?id=' + appID + '&country=es" >Lookup</a><br />');
</script>

This script takes the numeric ID and gives me 415321306.

So my question is how can I do the same thing but using PHP.

Best regards.

Answer 1

Who needs regex?

<?php
    $sURL = "http://itunes.apple.com/us/app/accenture-application-for/id415321306?uo=2&mt=8&uo=2";
    $appID = str_replace('id','',basename(parse_url($sURL, PHP_URL_PATH)));
    echo $appID; // output: 415321306
?>

Answer 2

Use PHP's explode() function instead of .split().

splitURL = sURL.split('/');  //JavaScript

becomes

$splitURL = explode('/', $sURL);  //PHP

An use preg_match() instead of .match().

$appID = preg_match("[0-9]*[0-9]", $splitURL);

I'm a little unclear on what you're doing with the length of the string, but you can get substrings in php with substr().
