php安装soap扩展
例：1、编译安装
解压对应php版本安装包
进入解压后的ext目录
phpize --生成configure文件，报以下错误，可以忽略

./configure --with-php-config=/usr/local/php5/bin/php-config --enable-soap
make
make install
注：
Installing shared extensions: /usr/local/php5/lib/php/extensions/no-debug-zts-20060613/
提示编译后的soap.so文件保存在了/usr/local/php5/lib/php/extensions/no-debug-zts-20060613/目录下。
2、修改php.ini
2.1 如果之前没有安装过extension，则需要将extension_dir = "./"改为extension_dir ="/usr/local/php5/lib/php/extensions/no-debug-zts-20060613/"，如果已经装过，这步之前应 该就已经改过了，也可以自定义到其它路径，一般使用默认路径。
2.2添加：
extension=soap.so
3、重启apache
phpinfo查看是否安装成功
