php 5，需要打开socket扩展

//socke操作类
class Socket {
private $host;//连接socket的主机
private $port;//socket的端口号
private $error=array();
private $socket=null;//socket的连接标识
private $queryStr="";//发送的数据
public function __construct($host,$port) {
if(!extension_loaded("sockets")){
exit("请打开socket扩展 ");
}
if(empty($host)) exit("请输入目标地址");
if(empty($port)) exit("请输入有效的端口号");
$this->host=$host;
$this->port=$port;
$this->CreateSocket();//创建连接
}
//创建socket
private function CreateSocket(){
!$this->socket&&$this->socket=socket_create(AF_INET, SOCK_STREAM, SOL_TCP);//创建socket
$r=@socket_connect($this->socket,$this->host,$this->port);
if($r){
return $r;
}else{
$this->error[]=socket_last_error($this->socket);
return false;
}
}
//向socket服务器写入数据并读取
public function wr($contents){
$this->queryStr="";
$this->queryStr=$contents;
!$this->socket&&$this->CreateSocket();
$contents=$this->fliterSendData($contents);
$result=socket_write($this->socket,$contents,strlen($contents));
if(!intval($result)){
$this->error[]=socket_last_error($this->socket);
return false;
}
$response=socket_read($this->socket,12048);
if(false===$response){
$this->error[]=socket_last_error($this->socket);
return false;
}
return $response;
}
//对发送的数据进行过滤
private function fliterSendData($contents){
//对写入的数据进行处理
return $contents;
}
//所有错误信息
public function getError(){
return $this->error;
}
//最后一次错误信息
public function getLastError(){
return $this->error(count($this->error));
}
//获取最后一次发送的消息
public function getLastMsg(){
return $this->queryStr;
}
public function getHost(){
return $this->host;
}
public function getPort(){
return $this->port;
}
//关闭socket连接
private function close(){
$this->socket&&socket_close($this->socket);//关闭连接
$this->socket=null;//连接资源初始化
}
public function __destruct(){
$this->close();
}
}
