Backwards compatible cloning from PHP5 to 4. At some point gonna post some experiences with BC in more detail. There’s a few grey areas to be resolved, like that zend.ze1-compatibility-mode (off by default) setting which, right now, is candidate for renaming, based on my experiences. Something like;
# mystery_bug_mode = On
In fact it’s seems generally possible to live without zend.ze1-compatibility-mode and still preserve BC, depending on what your code was doing.
