[PHP] Little regex help please...
Hello!
Here's a regex that I got off the web that I am trying to modify for my needs,
I suck at regex so desperately need some help.
Basically, am trying to get a remote webpage and get the value between the
title tags, note that it should get the values regardless if title is upper
or lower case (case insensitive)
?php
$data = file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
preg_match('/#title([^]*)/title#/iU',$data,$match);
$title=$match[1];
echo $title;
?
This is the error that i am getting when running the above:
Warning: preg_match() [function.preg-match]: Unknown modifier 't' in
C:\wamp\www\ezee\tests\get
_remote_title.php on line 3
TIA,
Ryan

Ryan,
I don't believe you need both the / and the # for delimiters in your
RegEx. Try using just # (since / is actually going to be in the text
you're searching for) like this:
?php
$data =
file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
preg_match('#title([^]*)/title#iU', $data, $match);
$title = $match[1];
echo $title;
?

Very true... but I think everything gets a bit convoluted when you escape your
forward-slashes instead of just choosing a more convenient
delimiter--especially when URLs are involved. I've seen a few regex that look
ridiculous for that very reason: /http:\/\/www\.asdf\.com\/blah\/foobar\.php/i
... looks like a zig-zaggy mess. :)

Hey Todd, Eric,
Thanks for replying.
I don't believe you need both the / and the # for delimiters in your

Ok, I changed it to:
?php
$data = file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
preg_match('/#title([^]*)\/title#iU',$data,$match);
$title=$match[1];
echo $title;

And this is the error i am getting:

Well that is a bit extreme, but I understand your point. If it were 1
character I'd still stick with /'s and escape one though.

Sorry forgot to include the list in my post to you
Here is another solution if you don't want to play around too much with
regex:
?php
$data = file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
$strt = strpos($data,title)+7;
$end = strpos($data,/title);
$len = $end - $strt;
$title= substr($data,$strt,$len);
echo $title
?
Produces:
YouTube - REALLY funny ad
As mentioned, you can probably neaten this up a bitregex may be too
complex for the simple requirement needed ?
But for fun, it will be nice to see get if preg_match can do it at some
stage :-)

preg_match('#title([^]*)/title#iU',$data,$match);
That'll do, Jim. :)
I also thought it worth mentioning that by telling a catch-all character
sequence (.*) not to be greedy, another viable solution would be this:
preg_match('#title(.*?)/title#iU', $data, $match);
The ? will stop it when it reaches /title through back-tracking.
Probably less-efficient in more complex regex patterns, but I find it
can help make the patterns more readable at-a-glance in regex-heavy code
blocks.
Sorry.. a bit OT.. and the OP has already been answered. Meh.
