Regex - whats wrong with this?

[fLUx1337]

Hey,

I've been trying to make this damn regex work for 3.5hours now, and so far - have nothing!

I need to preg_match a string for this, and get the number, in this case 47, out if it, but the foo variable wont be the same, so should be ignored:

<span class="cut"> ...&nbsp;</span><a href="blah.php?foo=bar&page=47">

preg_match('|\<span class\=\"do\"> ...&nbsp;<\/span><a href\=\"blah.php?foo=(.)&page=([^\"])"\>|', $contents, $matches);

Anyone know whats wrong?

Thanks

"...&nbsp" <- a dot is a wildcard in regex, so escape all three of those

"foo=(.)" <- that dot will only match a single character; use (.*) to match any number of characters

Thanks for your reply!

Although, either I don't understand what you mean, or something else in the expression isn't right:

preg_match('|\<span class\=\"do\"> \.\.\.\&nbsp;\<\/span><a href\=\"blah.php?foo=(.*)&page=([^\"])"\>|', $contents, $matches); 

Whats wrong with it now?

Thanks!

Dunno, I started fresh. This'll capture the foo and page values:

#\<span class=\"cut\"\> \.\.\.&nbsp;\<\/span\>\<a href=\"blah.php\?foo=(.*)&page=([0-9]*)\"\>#

Gave it a whirl at the regular expression tester to make sure it worked.

woo!

Thanks mate, I will compare it now to see what I did wrong...

Although, its outputting all the rest of the document after it too:

Array
(
    [0] => <span class="cut"> ...&nbsp; ......etc........
    [1] => d&page=47"> 47&nbsp; ......etc........
    [2] => 2
) 

You know why? Sure its just something simple...

Thanks!

Your input must not look like the string you said you wanted to match. The matches for that string are [1]=foo, [2]=47. Add a ^ at the beginning of the pattern and $ at the end and see if that's any better for ya.
