Description:
------------
Array returned by function pathinfo() contains wrong values when extra "." is 
introduced in the parameter, even though "." is a valid character of a query 
string.

Test script:
---------------
<php?
$test_url = "/test.php?q=".urlencode("hello this is a test 1.0");
echo "test_url:".$test_url.PHP_EOL;
var_dump(pathinfo($test_url));
?>

Expected result:
----------------
test_url:/test.php?q=hello+this+is+a+test+1.0
array(4) {
  ["dirname"]=>
  string(1) "\"
  ["basename"]=>
  string(35) "test.php?q=hello+this+is+a+test+1.0"
  ["extension"]=>
  string(26) "q=hello+this+is+a+test+1.0"
  ["filename"]=>
  string(4) "test"
}


Actual result:
--------------
test_url:/test.php?q=hello+this+is+a+test+1.0
array(4) {
  ["dirname"]=>
  string(1) "\"
  ["basename"]=>
  string(35) "test.php?q=hello+this+is+a+test+1.0"
  ["extension"]=>
  string(1) "0"
  ["filename"]=>
  string(33) "test.php?q=hello+this+is+a+test+1"
}
