Re: [PHP4BETA] changing all "php3" to "php4" ?

PHP4 is not going to be 100% backward compatible. We have already identified things that just won't be fixed. And second, PHP3 is stable. It will be a while before PHP4 is. The lack of a transition phase where you don't have to bet the farm on PHP4 will slow down the migration to PHP4. If it really is such a big job to make them run concurrently, the transistion phase will have to be done through cgi. > Second, you can't do it.

Both PHP3 and PHP4 compile as DSO's. If it weren't for a couple of symbol clashes, both could easily be loaded concurrently. And besides, none of this is a reason not to change "php3" strings to "php4" throughout the code even if it isn't for concurrency reasons. -Rasmus -- PHP 4 Beta
