侦听
# /usr/local/php/bin/php  /usr/local/apache2/htdocs/server.php

请求
# /usr/local/php/bin/php  /usr/local/apache2/htdocs/client.php

默认PHP是没有开启Socket的
 
#cd ./ext/sockets/
# /usr/local/php/bin/phpize
# ./configure --enable-sockets --with-php-config=/usr/local/php/bin/php-config
# make
# make install

php.ini修改配置
增加
extension=sockets.so
 
重启apache
# /usr/local/apache2/bin/apachectl restart

===================
Windows下的配置
修改php.ini
extension=php_sockets.dll
重启apache
cmd下起2个
php的安装目录

C:/php/php.exe   F:web/server.php
C:/php/php.exe   F:web/client.php
