Problem with a regular expression in PHP

I need to get this working:

PHP

First match should look for the following:

                  $pattern1 = "/<div rawurl\=\"(.*)\" class/"; // Add wildcard here as there will be 10 matches, we are only looking for one.
    开发者_运维问答              preg_match($pattern1, $file, $out1);

Then run a second check to see if our defined variable exists in the result from the first preg_match $out1,

                  $pattern2 = preg_quote("http://domain.com/extras/?possiblequery" ."/");
                  $pattern2 = "/".$pattern2."/";
                  if (preg_match($pattern2, $file, $out)); 
                    { return result

I have trouble coding up the regular expression for these two preg_match lines... I am pretty sure it's the first one with the wildcard.. Any help is welcome!

You need to specify the delimiters with the second parameter of preg_quote:

preg_quote("http://example.com/extras/?possiblequery", "/")

As far as I understand, the lack of ’?’ after ’.*’ seems suspect to me.

What do you call a widcard ?
