Alan and I ran up against this when working on PHP_Parser a long time ago. In fact, we found that the values assigned to tokens was non-determistic, and were able to get at least 3 different mappings of tokens => integer value on different systems. Our solution was to iterate over a set of integers known to be within the range of possibility, and then to use that to determine the correct integer value. You can see the result of the work in the PHP_Parser_Tokenizer class, which may be useful if you need the numbers. I have no freakin' idea why the token numbers are different in the *same* PHP version, but I can tell you that the intenral order of definition did indeed change in PHP 5 from PHP 4. This is actually in the Zend engine itself, and not in the tokenizer extension, which reflects this change rather than creates it. Greg
