Question

I want to read string from right to left. For example I want to get 50940775 from $game in below code.

I referred another stackoverflow question. They said to use $, but it is not working for me. I use below code.

$game = 'http://www.myspace.com/sdsf/1223232/videos/video/50940775black';

preg_match('/\/(.*?)black$/', $game, $match);
print_r($match[1]);

Note : $game Url are different like below

http://www.myspace.com/sdsf/1223232/black/video/50940775black
http://www.myspace.com/sdsf/1223232/videos/12345/50940775black
http://www.myspace.com/sdsf/1223232/videos/games129kj/5675999black

Answer 1

Since you want to get numbers, you can specify that you only want them ([0-9]+) instead of every thing (.*). With .* it will retrieve every thing between the first / found and black. So, in your case: /www.myspace.com/sdsf/1223232/videos/video/50940775black

Try this one:

$game = 'http://www.myspace.com/sdsf/1223232/videos/video/50940775black';

preg_match('/\/([0-9]+)black$/', $game, $match);
print_r($match[1]);

Edit:

In fact, it’s hard to read from right to left. What you can do is explode the url by / and then use the last part to apply your regex:

<?php

$game = explode('/', 'http://www.myspace.com/sdsf/1223232/videos/video/50940775black');
$data = end($game);

preg_match('/(.*?)black$/', $data, $match);
print_r($match[1]);
