preg_match matching multiple matches

I'm trying to use preg_match to extract info from

href="domai开发者_开发技巧n.com/subdir/?key=value

The info I want are

1. domain.com
2. subdir
3. key
4. value

Can someone suggest what is the correct way to write the preg_match statement?

Thanks!

use this as your regex

/href="(.+..+?)/(.+?)/(\?.+?=.+)"/

that should work

preg_match('/href="(.+\..+?)\/(.+?)\/(\?.+?=.+)"/', $input, $matches);
echo "First Match: {$matches[0]}\n";
