c++开发php5 扩展
1，准备开发环境
源码安装nginx, php, mysql
nginx安装路径: /opt/server/nginx 源码路径: /home/leon/Downloads/nginx-1.5.6
php路径: /opt/server/php 源码路径: /home/leon/Downloads/php-5.3.10
mysql路径: /opt/server/mysql 源码路径: /home/leon/Downloads/mysql-5.1.63
2，开发PHP扩展
a) 创建扩展工程
cd /home/leon/Downloads/php-5.3.10/ext/
./ext_skel --extname=php5cpp
cd php5cpp/
mv php5cpp.c php5cpp.cpp
b) config.m4
PHP_ARG_ENABLE(php5cpp, whether to enable php5cpp support,
Make sure that the comment is aligned:
[--enable-php5cpp Enable php5cpp support])
if test "$PHP_PHP5CPP" != "no"; then
PHP_REQUIRE_CXX()
PHP_SUBST(PHP5CPP_SHARED_LIBADD)
PHP_ADD_LIBRARY(stdc++, 1, PHP5CPP_SHARED_LIBADD)
PHP_NEW_EXTENSION(php5cpp, php5cpp.cpp, $ext_shared)

e) 编译安装
phpize
./configure --with-php-config=/opt/server/php/bin/php-config
make
sudo make install
f) 修改php.ini
sudo service php-fpm stop
sudo gedit /opt/server/php/etc/php.ini
加入 extension=php5cpp.so
sudo service php-fpm start
