underscore

New Comment:
filter_var($var, FILTER_VALIDATE_URL) doesn't handle IPv6 addresses so I
can't use
it. I've gotten around the problem. I just didn't realize _ was
replacing
invalid characters.

php.net/parse_url explains all of this:
"This function is not meant to validate the given URL, it only breaks it
up into
the above listed parts. Partial URLs are also accepted,
parse_url() tries its best to parse them correctly."
"The URL to parse. Invalid characters are replaced by _."
filter_var($var, FILTER_VALIDATE_URL) should do what you're looking for.

Description:
------------
The parse_url function turns the tab character into an underscore. This
turns an invalid URL into a valid one. If you are attempting to
validate user input with parse_url then it will pass validation even
though tab is an invalid character in a host name or FQDN. It may be
difficult to see in the example below but there is a tab.
Test script:
---------------
<?php
$host = "http://test url";
var_dump(parse_url($host));
?>
Expected result:
----------------
array(2) { ["scheme"]=> string(4) "http" ["host"]=> string(8) "test url"
}
or
array(2) { ["scheme"]=> string(4) "http" ["host"]=> string(8)
"test\turl" }
Actual result:
--------------
array(2) { ["scheme"]=> string(4) "http" ["host"]=> string(8) "test_url"
}
