Question

How do I write the following javacript code in php:

var ShareImageIdVar = location.href.match(/\d+/);

there is a number in the url that I want to store it in the variable ShareImageIdVar.

an example of a possible url:

http://www.mysite.com/5.php
http://www.mysite.com/41.php
http://www.mysite.com/547.php
http://www.mysite.com/2145.php

Answer 1

you js code is identify the first numerical string from all string

<script type="text/javascript">
var str = 'adsdf12323sad678jhgj';
var ShareImageIdVar = str.match(/\d+/);
alert(ShareImageIdVar);
</script>

try this in PHP

$string = $_SERVER['PHP_SELF'];
$number = preg_replace("/[^0-9]/", '', $string);
