Stefan Neufeind (http://pear.php.net/user/neufeind) has commented on the proposal for PHP::PHP_Compatibility. Comment: Though I haven't yet had time for a test, as we've already discussed I'm much in favor of such a package. It would be a nice option to be able to check which lines of code make it dependent on certain versions, so that it's just one call that demands latest php-release and everything else will run fine under 4.2.0 you have a chance to maybe workaround that one line to be far more compatible with not too much work (where possible).

Stefan, Narrowing it down to the line is impossible from tokens, AFAIK, HOWEVER I could make it keep an array like: functions => array('4.1.0' => array('some_func_added_in_4.1.0','foo'), '4.3.0' => array('some_func_added_in_4.3.0','bar')); It could *even* create an array of things that won't run on the current install... either because the extension isn't loaded or because the version doesn't have X functions. I also want to make it check for constants like __FILE__ and __LINE__ - and what about superglobals? I think that may be too costly. - Davey
