使用正则表达式在url中获取02x02的链接

Question

I have a little problem. I'm trying to learn regex, but I cant solve this problem. I have a list of urls with this pattern:

http://domain.com/something/03x05/something/something.html
http://domain.com/something/something/something.html
http://domain.com/something/02x02/something/something.html
etc...

So I need to extract URL's with "03x05" or "02x02". I tried to use "/[0-9]x[0-9]/" but I don't get any url.

Can you help me?

For something quick, try the following regex:

.*?[0-9]x[0-9].*

Explanation:

.*?   # match any character except newline (lazily) 
[0-9] # character class matching any digit
x     # literal character 'x'
[0-9] # character class matching any digit
.*    # match any character except newline (greedily)

Code:

preg_match_all('/.*?[0-9]x[0-9].*/', $text, $matches);
print_r($matches[0]);

Output:

Array
(
    [0] => http://domain.com/something/03x05/something/something.html
    [1] => http://domain.com/something/02x02/something/something.html
)
