I don't really know what I'm talking about, but nobody has answered yet... For starters, not all extensions are thread-safe. I would expect that to mean that anything actively using those extensions saved state in another thread is a segfault waiting to happen. For security reasons and sheer plain cussedness, I don't think you're going want and/or get any resource (mysql connection/result/etc, gd images, file handles, etc) survive to the next thread. A mysql connection, for example, is opened with a specific user/pass. Another thread picking this up could probably abuse that, as I understand it. Finally, your question begs another question: Why do you want to do this? -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
