I want to perform a regex using grouping. I am only interested in the grouping, its all I want returned. Is this possible?

$haystack = '<a href="/foo.php">Go To Foo</a>';
$needle = '/href="(.*)">/';
preg_match($needle,$haystack,$matches);
print_r($matches);

//Outputs
//Array ( [0] => href="/foo.php">  [1] => /foo.php ) 

//I want:
//Array ( [0] => /foo.php )
