经常有朋友会对php的socket应用充满疑惑，本文就以实例代码作一讲解，，希望能对初学php的朋友起到一点帮助作用
具体代码如下：
1.服务器端代码:
$name=$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
2.客户端代码:
$name=$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
注意事项:服务器端请用cli模式运行,cgi模式会超时,这是新手常喜欢犯的错误。那么什么是cli模式呢？简单的说就是用命令行去执行,而不要用游览器打开,否则会超时的！
