implementing new PHP functions in C

I understand that enough things have changed in PHP4 over PHP3 that the document for PHP3 that describes what to do add functions to PHP using C may not be useful, or at least not authoritative. Has anyone started working on such a document for PHP4 yet? Or has anyone put together a function package that adds on to PHP4 (isn't part of the PHP distribution) in C (not C++) that does things the "right" and intended ways which could be used as an example? I have numerous library functions I have written in C, and I would like to implement them in PHP in some way (there would be some differences as many of them work with pointers, or otherwise do things specific to C). The issues I probably need to find out (hopefully the documentation will fill me in on what I neglect here) about are: 1. How best to link the functions in. 2. How to access the data constructs in PHP, especially arrays. 3. How to trap exit time cleanups (essential in mod_php to avoid memory leakage). One of my big concerns is the way of linking in. I see two big approaches to this. One is to integrate the functions directly into the single binary image at compile/link time, so the functions "just work" with not extra efforts on the part of the programmre. The other is to make them dynamic. But it appears that PHP doesn't do dynamic exactly the same way C does, in that, you still have to add something to PHP at compile time to know about the functions in the first place (this I gather from having had to compile in add-ons even though they used dynamica libraries, which seemed rather pointless to me). I started in PHP at PHP4 beta, and have already put some pages together in PHP using PHP4 features, so going back to PHP3 just because there is more documentation available is not an option. PHP4 is the future so I'll stick with it (besides, it works fine for me, aside from the lack of some of my custom functions). -- | Phil Howard - KA9WGN | for headlines that | Just say no to absurd patents | | phil-nospam@ipal.net | really matter: | Boycott Amazon.Com (AMZN) | | Dallas - Texas - USA | linuxhomepage.com | Shop http://bn.com/ instead |
