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
/**

*/
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:
";//server端输出当前正在连接的客户端数量
echo "current connection:{$count}
";
//接受客户端传过来的字符串
$msg=$this->read($client_socket);
echo "client:{$msg}
";
//server向客户端传值
$my_msg="I am fine,think you
";
$this->send($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
