Ah. I must have been dreaming then.. :)
I remember that someone submitted some bug report about this very issue.
Anyway, now I see that there really is good reason having that
version (PHP_#ext#_API_NO ?) after all. And having that..we should
propable start moving those extensions one by one into PEAR?
Maybe we could then roll out two packages, one for core and one for
the extensions?
And btw. Why not have a function in PHP core that can be used to get the
desired extensions remotely from pear.php.net? If we have a
PHP_#ext#_API_NO, running a 'update_php_extensions()' would
go and grab the updated (if the extension HAS been updated) one..etc..
(I'm just thinking out loud..ignore me :)
