note 41506 rejected from opl.license by tomsommer

Note Submitter: shadedecho ---- First of all, this sounds rather inane to ask here, but what license is PHP actually distributed under? is it GNU GPL? is it BSD? other? I'm also curious about a few licensing issues. If i write a library of functions, objects, etc, for use as part of PHP applications (web or server), similar to something like PEAR or whatever, the code that i write it in obviously by necessity being written in PHP, do i have to distribute/publish that library under the same terms of license as PHP itself is distributed? and do i have to distribute PHP along with it? In other words, is a program/script written IN the language that the PHP engine interprets considered a derivative work of PHP? what if I was compiling the PHP using the Zend engine? would that have to be distributed under the same terms as the Zend engine? OR, as I am hoping, is a derivative work of PHP only considered something written to modify the PHP engine itself, such as an extension, a revision of the Zend engine, the module that Apache loads PHP with, etc etc? (and as a side note, did I violate licensing issues or copyrights by using the terms PHP, Zend, etc in this post?)
