Question

problem accessing to a variable in object

Answer 1

A:

Use a temporary variable to hold the matches:

private function grab_title_from_curl ($pull){
    $matches = array();
    preg_match("/<meta name=\"title\" content=\"(.*?)\"/", $pull, $matches) ;
    $data['title'] = $matches[0];
    return $data;
}

Based on your new edit I see how you're doing it. In that case JoostK's answer above should be correct. It's good practice to declare your variables before using them.

the code breaks! everytime!

The ampersand is there because I pass the variable by reference. In PHP it doesn't matter (as far as I know) whether you do it or not, however now I can clearly see that the variable is a reference, not having to look it up in the documentation.

Answer 2

+1 A:

Based on your edit, this should work:

private function grab_title_from_curl ($pull){
    $data = array();
    preg_match("/<meta name=\"title\" content=\"(.*?)\"/", $pull, &$data);
    return $data[0];
}

don't works, and also breaks the array:<code>Array( [type] => yahoo [id] => 613478/2923165 [title] => </code>

greenbandit 2010-09-01 23:29:08
