Alright, so I'm currently working on parsing an RSS feed. I've gotten the data I need no problem, and all I have left is parsing the game title.
Here is the code I currently have (ignore the sloppiness, it is just a proof of concept):
<?php
$url = 'http://raptr.com/conexion/rss';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$xml = new SimpleXMLElement($result);
$lastgame = $xml->channel->item[0]->description;
preg_match('[a-zA-Z]+</a>.$', $lastgame, $match);
echo $match;
?>
Everything was working great, but then I started getting this error:
Warning: preg_match() [function.preg-match]:
Unknown modifier '+' in raptr.php on line 14
The only thing I have left is to strip out the closing anchor tag and the period, but I can't seem to figure out why it isn't liking the '+'. Any ideas?
Edit: This should not be marked as a duplicate as it was asked two years before the other question.
You need to use delimiters with regexes in PHP. You can use the often used /, but PHP lets you use any matching characters, so @ and # are popular.
If you are interpolating variables inside your regex, be sure to pass the delimiter you chose as the second argument to preg_quote().
Try this code:
preg_match('/[a-zA-Z]+<\/a>.$/', $lastgame, $match);
print_r($match);
Using / as a delimiter means you also need to escape it here, like so: <\/a>.
UPDATE
preg_match('/<a.*<a.*>(.*)</', $lastgame, $match);
echo'['.$match[1].']';
Might not be the best way...
May be this will be usefull for u: ReGExp on-line editor
This happened to me because I put a variable in the regex and sometimes its string value included a slash. Solution: preg_quote.
