preg_match question

[Codemunkie]

Hello.

 

I'm trying to use preg_match to get a large amount of data from a website, is it possible to do this? It's html so i was hoping for line breaks etc.

 

The site source is below, which is what i'm wanting to retrieve.

<p> <strong>Fiora, The Grand Duelist</strong></p>

<li><strong>Riposte </strong>- Fiora's Attack Damage is increased. When activated, Fiora parries the next basic attack and reflects magic damage back to the attacker. Works against champions, monsters, and large minions.</li>

Here is my current php, that doesn't seem to work. (var p -> 'fiora-patch-notes')

$content = file_get_contents("http://na.leagueoflegends.com/news/" . $_GET['p']);
$regex = '#frameborder="0" allowfullscreen></iframe></p>
(.*?)
<p><a href="http://euw.leagueoflegends.com/board/showthread.php?p=#';
preg_match($regex, $content, $match, PREG_PATTERN_ORDER);
echo $match;

 

Note that my regex searches for the last bit of the first line, and the first bit of the last line in the page source. There's more source but i didn't see any point in posting it.

 

I know it's going to be something really obvious, i'm not used to working with preg match.

 

Thanks.

It doesn't seem like Riot wants you to scrape their pages.

1)  Scraping this website is against their ToS and I'm therefore closing this thread.

 

2)  You must add modifiers after your closing delimiter to get your regex to match mulitple lines.  Specifically add an 'm'
