Description:
------------
When passing a string containing 8 bytes that represents hexadecimal data such as 'ffffffff' to a user function that utilizes func_get_arg() or func_get_arg(), values become unavailable (zero length string) while func_num_args() will show that the value existed.

Configure Line "'./configure' '--with-mysql=/usr/local/mysql' '--with-ftp' '--enable-sockets' '--with-apxs2=/usr/local/apache2/bin/apxs'"

Apache 2.0, standard config + frontpage extensions. Frontpage extensions not active on this virtualhost.
Standard INI, with the exception of ASP TAGS.

Reproduce code:
---------------
function binlogdata() {
	global $DB, $scbinlogtable;
	$args = func_get_args();
	$results = '';
	foreach ($args as $key => $value) {
		if ($key == 0) {
			$results = $results.'<API>'.$value.'</API>';
		} else {
				$results = $results.'<PARM'.$key.'>'.$value.'</PARM'.$key.'>';
		}
	}
	return $results;
}

$fetch['test1'] = 'thisisok';
$fetch['test2'] = 'ffffffff';

echo binlogdata('PlayerLimit',$fetch['test1'],$fetch['test2']);



Expected result:
----------------
// The expected result is 	"<API>PlayerLimit</API><PARM1>thisisok</PARM1><PARM2>ffffffff</PARM2>";


Actual result:
--------------
// The actual result is 	"<API>PlayerLimit</API><PARM1>thisisok</PARM1><PARM2></PARM2>";
