php---第一个扩展开发

下载php源码 http://php.net/downloads.php
1.编译php

cd /home/php5.6.22./configure --prefix=/usr/local/phptest/ --enable-debug --enable-maintainer-zts '--enable-fpm' '--with-config-file-path=/usr/local/phptest/etc'make && make install

2.利用php自带的扩展模板生成器生成模板

cd /home/php5.6.22/ext/[root@iZ23v4z44uqZ ext]# ./ext_skel./ext_skel --extname=module [--proto=file] [--stubs=file] [--xml[=file]]           [--skel=dir] [--full-xml] [--no-help]  --extname=module   module is the name of your extension  --proto=file       file contains prototypes of functions to create  --stubs=file       generate only function stubs in file  --xml              generate xml documentation to be added to phpdoc-svn  --skel=dir         path to the skeleton directory  --full-xml         generate xml documentation for a self-contained extension                     (not yet implemented)  --no-help          don't try to be nice and create comments in the code                     and helper functions to test if the module compiled[root@iZ23v4z44uqZ ext]# ./ext_skel --extname=xing2233Creating directory xing2233Creating basic files: config.m4 config.w32 .gitignore xing2233.c php_xing2233.h CREDITS EXPERIMENTAL tests/001.phpt xing2233.php [done].To use your new extension, you will have to execute the following steps:1.  $ cd ..2.  $ vi ext/xing2233/config.m43.  $ ./buildconf4.  $ ./configure --[with|enable]-xing22335.  $ make6.  $ ./sapi/cli/php -f ext/xing2233/xing2233.php7.  $ vi ext/xing2233/xing2233.c8.  $ makeRepeat steps 3-6 until you are satisfied with ext/xing2233/config.m4 andstep 6 confirms that your module is compiled into PHP.
