欢迎大家讨论如何开发php的扩展模块，呵呵

Creating a standalone skeleton extension
First, make sure you have the most recent versions of bison, flex, autoconf, automake, and libtool installed. Along with gcc, and make, of course. It is also a good idea to build and install the command line version of PHP before you continue. It is much easier to debug a single standalone php binary than the module version embedded in Apache.

% cd php4/ext
% ./ext_skel --extname=foo
Creating directory foo
Creating basic files: config.m4 Makefile.in .cvsignore foo.c
php_foo.h CREDITS EXPERIMENTAL
tests/001.phpt foo.php [done].
% cd foo
% ls
config.m4 CREDITS EXPERIMENTAL foo.c
foo.php Makefile.in php_foo.h tests/
% phpize
% ls
acinclude.m4 config.guess* config.sub* CREDITS
foo.c ltmain.sh* mkinstalldirs aclocal.m4
config.h.in configure* dynlib.m4 foo.php
Makefile.in php_foo.h build/ config.m4
configure.in EXPERIMENTAL install-sh missing
tests/
% cd ..
% mv foo /tmp
% cd /tmp/foo

[yorgo]

Compiling the test skeleton extension

% cd /tmp/foo
% vi config.m4

The config.m4 file
The config.m4 file adds any extension-specific configuration options. If your extension relies on external libraries and header files, you need to define those in this file and uncomment the --with-foo section. If your extension does not rely on any external libraries, uncomment the --enable-foo section.

configure, build and install

% ./configure
% make
% cp modules/foo.so /usr/local/lib/php


Testing your extension
The ext_skel script created a sample foo.php script. A quick way to check if your extension is working is to edit this script and add dl('foo.so') to the top. Then run it through your command-line PHP parser:

% php -q foo.php
Congratulations!
You have successfully modified ext/foo/config.m4.
Module foo is now compiled into PHP.

zend有一些规范 ：http://www.zend.com/apidoc/
不过，我觉得没什么特别的东西值得写！大家讨论以下！
