phpsocketclient以及server样例

一个菜鸟朋友,突然问了我这个问题...如今稍稍有点时间,就写了一个简单的样例给他,顺便贴上来

server端:

<?

php
/**
 * @author 邹颢	[e-mail]
 */
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($error);
	}
	/**
	 * 開始进行socketserver端监听端口
	 */
	public function start(){
		// 创建端口
		if (($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;
				//把新来的用户增加 客户端数组里
				$this->_client_socket_list[]=$client_socket;
				echo "new connection:\r\n";//server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";
				//server向客户端传值
				$my_msg="I am fine,think you\r\n";
				$this->send($client_socket,$my_msg);
			}
			/**
			 * 这段代码给你參考,用来推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, $buffer, 2048, 0 ); // 接受一下客户端信息,假设为0代表断开连接
					if ($len < 7) {
						//这里写是去连接的客户端业务
					}
				}
			}
			 */

		}while(true);
	}
	/**
	 * 发送数据给客户端
	 */
	public function send($client_socket,$str){
		return socket_write ( $client_socket,$str, strlen ( $str ) );
	}
	/**
	 * 从客户端接受数据
	 */
	public function read($client_socket){
		return socket_read ( $client_socket, 8192 );//8192实际代表的接受长度,我用819292表示长一点,这样长一点的字符串也能够接受到,不到8192也没关系,会自己主动识别
	}

}
$socket_server =new SocketServer();
$socket_server->start();//開始监听

客户端:

<?

php
/**
 * @author 邹颢	[e-mail]
 */
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($error);
	}
	/**
	 * 開始进行socketserver端监听端口
	 */
	public function start(){
		// 创建端口
		if (($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;
				//把新来的用户增加 客户端数组里
				$this->_client_socket_list[]=$client_socket;
				echo "new connection:\r\n";//server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";
				//server向客户端传值
				$my_msg="I am fine,think you\r\n";
				$this->send($client_socket,$my_msg);
			}
			/**
			 * 这段代码给你參考,用来推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, $buffer, 2048, 0 ); // 接受一下客户端信息,假设为0代表断开连接
					if ($len < 7) {
						//这里写是去连接的客户端业务
					}
				}
			}
			 */

		}while(true);
	}
	/**
	 * 发送数据给客户端
	 */
	public function send($client_socket,$str){
		return socket_write ( $client_socket,$str, strlen ( $str ) );
	}
	/**
	 * 从客户端接受数据
	 */
	public function read($client_socket){
		return socket_read ( $client_socket, 8192 );//8192实际代表的接受长度,我用819292表示长一点,这样长一点的字符串也能够接受到,不到8192也没关系,会自己主动识别
	}

}
$socket_server =new SocketServer();
$socket_server->start();//開始监听

注意事项:server端请用CLI模式执行,cgi模式会超时,新手常喜欢犯的错误.什么是CLI模式,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
