preg_replace with Regex - 在URL中查找数字序列

Question

I'm a regex-noobie, so sorry for this "simple" question:

I've got an URL like following:

http://stellenanzeige.monster.de/COST-ENGINEER-AUTOMOTIVE-m-w-Job-Mainz-Rheinland-Pfalz-Deutschland-146370543.aspx

what I'm going to archieve is getting the number-sequence (aka Job-ID) right before the ".aspx" with preg_replace.

I've already figured out that the regex for finding it could be

(?!.*-).*(?=\.)

Now preg_replace needs the opposite of that regular expression. How can I archieve that? Also worth mentioning:

The URL can have multiple numbers in it. I only need the sequence right before ".aspx". Also, there could be some php attributes behind the ".aspx" like "&mobile=true"

Thank you for your answers!

Answer 1

You can use:

$re = '/[^-.]+(?=\.aspx)/i'; 
preg_match($re, $input, $matches);
//=> 146370543

This will match text not a hyphen and not a dot and that is followed by .aspx using a lookahead (?=\.aspx).
