Description:
------------
The url wrapper support in php does not ignore case of the scheme part of URLs.

According to RFC-3986 (aka. STD-66), Sec. 3.1, the scheme in an URL is case-insensitive and therefore should be matched in a case-insensitive manner.

(See http://www.rfc-editor.org/rfc/std/std66.txt)

This problem is present in both, php-4.4.4 and php-5.1.6.

PHP compiled from source with ./configure  --disable-cgi --enable-cli --disable-ipv6 --disable-all --without-pear



Reproduce code:
---------------
This will not work:

<?
error_reporting(E_ALL);
echo file("hTtp://www.php.net");
?>


This works as expected:
<?
error_reporting(E_ALL);
echo file("http://www.php.net");
?>

Note the capital "T" in "hTtp://" in the first example.

Expected result:
----------------
First example should show the same behaviour as the second one. Both examples should complete without error.



Actual result:
--------------
First example returns:

Notice: file(): Unable to find the wrapper "hTtp" - did you forget to enable it when you configured PHP? in xxx on line 3

Warning: file(hTtp://www.php.net): failed to open stream: No such file or directory in xxx- on line 3
