Nice catch!

This can be fixed by adding a len == 0 check after the while loop in http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_language_scanner.l#1515
(and returning 0 in that case).

Description:
------------
These echoes 4:
echo (0x00+2);
echo (0x00+0x02);
but they should echo 2! This echoes 2 as expected:
echo (0x00 + 2);

Test script:
---------------
echo (0x00+2);

Expected result:
----------------
2

Actual result:
--------------
4
