How to extract specific value between slashes in a URL?

Question

I'm working on *.xml file containing pictures.

I need to extract product ID from the first image URL https://images.example.co.uk/products/1835/1835776/large2/29203852.jpg which for this example is 1835776.

Question:

What is the correct regular expression to achieve this, considering that some elements within the image URL seperated with / are different for each product (XXXXX)?

https://images.example.co.uk/products/XXXXX/[I-WANT-THIS-ELEMENT]/large2/XXXXXXXX.jpg

I would just use a class like NET_absolute, and feed it your url and then all you would have to do is call $url->getPart ( 2 ); — Stephanie Temple, Jan 29 '19 at 14:05

Presuming the URL will always be in the same format:

$url = "https://images.example.co.uk/products/XXXXX/[I-WANT-THIS-ELEMENT]/large2/XXXXXXXX.jpg";
$url = explode('/',$url);
$id = $url[5];
echo $id;
