Regular Expression of PHP crawler (i)

1.

I don't know how to match it.

Later found also no character set GBK.

$matches =array ();
$reg = "/<span>???????? <\/span> ([^ (<BR)]*) <br \/>/";
$reg = "/<span> album name:<\/span> ([^ (BR)]*) <br \/>/";

2.

Preg_match ($reg, $subject, $matches);
Print_r ($matches);

How does the following code match the album name Seek Mei?

<span> Album name:</span> mei <br/>

([^ (BR)]*) Looking for a name that does not contain a BR does not have the skill to start without thinking.

return value

$matches [0] entire character

$matches [1] The character of the first parenthesis this is really the trick. It's a good design.
