phpsocket客户端以及服务器例子
一个菜鸟朋友,突然问了我这个问题...现在稍稍有点时间,就写了一个简单的例子给他,顺便贴上来
服务器端:
<?php /** * @author 邹颢 [email protected] */class SocketServer{ private $_port='9000'; private $_address='127.0.0.1'; private $_client_socket_list=array(); public function __set($name,$val){ $this->$name=$val; } private function _showError($error){ exit($error); } /** * 开始进行socket服务器端监听端口 */ public function start(){ // 创建端口 if (($sock = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP )) === false) { $this->_showError("socket_create() failed :reason:" . socket_strerror ( socket_last_error () )); } // 绑定 if (socket_bind ( $sock, $this->_address, $this->_port ) === false) { $this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) )); } // 监听 if (socket_listen ( $sock, 5 ) === false) { $this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ) ); } do { //当有一个客户端连接的时候 if ($client_socket=socket_accept ( $sock )) { $count = count ( $this->_client_socket_list ) + 1; //把新来的用户加入 客户端数组里 $this->_client_socket_list[]=$client_socket; echo "new connection:\r\n";//服务器端输出当前正在连接的客户端数量 echo "current connection:{$count}\r\n"; //接受客户端传过来的字符串 $msg=$this->read($client_socket); echo "client:{$msg}\r\n"; //服务器向客户端传值 $my_msg="I am fine,think you\r\n"; $this->send($client_socket,$my_msg); } /** * 这段代码给你参考,用来判断是否有客户端主动失去连接 else{ foreach ( $this->_client_socket_list as $socket ) { $len = socket_recv ($socket, $buffer, 2048, 0 ); // 接受一下客户端信息,如果为0代表断开连接 if ($len start();//开始监听<?php /** * @author 邹颢 [email protected] */class SocketServer{ private $_port='9000'; private $_address='127.0.0.1'; private $_client_socket_list=array(); public function __set($name,$val){ $this->$name=$val; } private function _showError($error){ exit($error); } /** * 开始进行socket服务器端监听端口 */ public function start(){ // 创建端口 if (($sock = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP )) === false) { $this->_showError("socket_create() failed :reason:" . socket_strerror ( socket_last_error () )); } // 绑定 if (socket_bind ( $sock, $this->_address, $this->_port ) === false) { $this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) )); } // 监听 if (socket_listen ( $sock, 5 ) === false) { $this->_showError("socket_bind() failed :reason:" . socket_strerror ( socket_last_error ( $sock ) ) ); } do { //当有一个客户端连接的时候 if ($client_socket=socket_accept ( $sock )) { $count = count ( $this->_client_socket_list ) + 1; //把新来的用户加入 客户端数组里 $this->_client_socket_list[]=$client_socket; echo "new connection:\r\n";//服务器端输出当前正在连接的客户端数量 echo "current connection:{$count}\r\n"; //接受客户端传过来的字符串 $msg=$this->read($client_socket); echo "client:{$msg}\r\n"; //服务器向客户端传值 $my_msg="I am fine,think you\r\n"; $this->send($client_socket,$my_msg); } /** * 这段代码给你参考,用来判断是否有客户端主动失去连接 else{ foreach ( $this->_client_socket_list as $socket ) { $len = socket_recv ($socket, $buffer, 2048, 0 ); // 接受一下客户端信息,如果为0代表断开连接 if ($len start();//开始监听
