php中socket实现GET与POST异步提交数据

#cd /home/php5.2.1/ext/sockets
#/server/php/bin/phpize
#./configure --prefix=/usr/local/php/lib --with-php-config=/server/php/bin/php-config --enable-sockets
#make
#make install

再修改/usr/local/php/etc/php.ini文件
#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/" (php5.4版本以上不用加扩展路径)
