php使用socket编程示例

2个php测试文件
server.php

<?php
//phpinfo();
//确保在连接客户端时不会超时
set_time_limit(0);

$ip = '127.0.0.1';
$port = 1935;

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

extension=sockets.so

# /usr/local/apache2/bin/apachectl restart

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
