It is not very difficult to write PHP Module, and the reference articles are:
Write your own PHP extension function
Zend Manual
This article mainly said the compilation process
1 Locate the source code of PHP, decompress (if you have installed the original installation source code)
2 Use the tool "ext_skel" to initialize the module code, this tool is written for you, some of the necessary code: {phpSRC} / ext / ext_skel _extName = module name first go to {phpSRC} / ext / directory, then execute
-------------
./ext_skel --extName = my_module
-------------
This tool will create a directory that is the same as the module name in ext /, and creates some related code. 3 Modify config.m4 files
File Location: {PHPSRC} / EXT / Module Name /config.m4
Modifying method: Remove and the module related to the several lines of comments (3 lines) (remove DNL, optional with, enable, I chose with whom, because the letters are less: P)
4 Modify the generated code, create your own functions
How to modify this section can refer to Zend Manual to make your own functional function
I added a function weiping (); output "Welcome to my homepage:
http://www.wmsp.org "

5 Return to {PHPSRC} Run Tool Buildconf
Sometimes it may be enforced with buildconf --force
6 Configure reconfiguration
./configure --with-module name
7 Make
Don't say more, play MAKE
8 test
Write a test function in your module, then use the just compiled PHP to execute
9 recompile Apache, join the new PHP module libphp4.a
