[RESOLVED] Help with preg_match regex

Code:

---

$regex = '#[0-9]{1,9}(?=">' . $name . '</a>)#';
preg_match($regex, $html, $matches);
echo $matches[0];

---

The variable $name is in my test case:

Code:

---

house

---

And the $html contains this string:

Code:

---

<a href="addonentry.php?fsid=54334">house</a>

---

My goal is to get the id you can see there, but it just won't work.
lol I am used to C#, the regex there makes sense compared to this :P

Seems to be working for me:

PHP Code:

---

$name = 'house';
$html = '<a href="addonentry.php?fsid=54334">house</a>';

$regex = '#[0-9]{1,9}(?=">' . $name . '</a>)#';
preg_match($regex, $html, $matches);
echo $matches[0];

//echos 54334

Is there more to your code?

Yes there is, sorry for not posting it.
The $html variable, as you may have guessed, contains the html of a whole page, fetched using file_get_contents.

It seems that if I put the real html in the $html variable, the thing breaks.

PHP Code:

---

$name = "ttt_giant_daycare_V2.zip";
$url = "http://freesteam.org/gmod/search.php?searchterm=" . $name;
$html = file_get_contents($url);

$regex = '#[0-9]{1,9}(?=">' . $name . '</a>)#';
preg_match($regex, $html, $matches);
echo $matches[0];

That is the whole code, my fault for not posting it.
It can also be executed here, at my dev server:
http://fredrikblomqvist.developer.se/dev/getaddon.php

If you view the source of the page you're retrieving, you can see the problem; here's the relevant piece:

Code:

---

<a href='addonentry.php?fsid=38635' >ttt_giant_daycare_V2.zip</a>

---

Your pattern is looking for the href to be enclosed with double quotes; this markup's using single quotes. There's also a space between the enclosed href and the tag delimiter. If you want to match this specific case, you could use this pattern instead:

Code:

---

$regex = "#[0-9]{1,9}(?=' >" . $name . "</a>)#";

---

Or if you wanted to keep it flexible, something like this also works:

Code:

---

$regex = "#[0-9]{1,9}(?=(\"|')(\s+)?>" . $name . "</a>)#";

---

god damn it, must have overseen that.
Thanks a lot for finding the problem and giving me a tip on the regex :)
Do you happen to know any good regex builder site for preg_match?
I have this wonderful thing for C# regexes:
http://gskinner.com/RegExr/

The best with that one is that it has a list with all the variables and so on to the right where you fast and easy can check how to do stuff :)
