Description:
------------
When using preg_match or, preg_match all, it seems to be adding the array key as the value, instead of the matched value for instance, instead only the first match, 

This problem does NOT exist on version 4.3.9

Reproduce code:
---------------
$string='<a href="http://www.example.com">Some Text</a>';

		preg_match_all('/<\s*a\s*href="([^\"]+)"\s*>([^>]*)<\/a>/i', $lines, $main_array, PREG_SET_ORDER);
		foreach($main_array as $main_code){
			$url = $main_code[1];
			$text = $main_code[2];
			echo "$url $text\n";
		}
print_r($main_array);

Expected result:
----------------
if $match[1] through  $match[4] equals "abc"

$match[1] returns "0"
$match[2] returns "1"
$match[3] returns "2"
$match[4] returns "3"



Actual result:
--------------
if $match[1] through  $match[4] equals "abc"

$match[1] should return "abc"
$match[2] should return "abc"
$match[3] should return "abc"
$match[4] should return "abc"
