$argc and $argv global variables are registered only in CLI mode and under $_SERVER[] in other case. (This is done because register_globals was removed and assumed - off).
Took the old PHP 3 regression testing framework and rewrote it in PHP.
Should work on both Windows and UNIX, however I have not tested it on
Windows. See tests/README for how to write tests. Added the PHP 3
tests and converted most of them.
