很簡單的一個socket用戶端PHP類

php 5，需要開啟socket擴充 //socke操作類 class Socket { private $host;//串連socket的主機 private $port;//socket的連接埠號碼 private $error=array(); private $socket=null;//socket的串連標識 private $queryStr="";//發送的資料 public function __construct($host,$port) { if(!extension_loaded("sockets")){ exit("請開啟socket擴充 "); } if(empty($host)) exit("請輸入目標地址"); if(empty($port)) exit("請輸入有效連接埠號碼"); $this->host=$host; $this->port=$port; $this->CreateSocket();//建立串連 } //建立socket private function CreateSocket(){ !$this->socket&&$this->socket=socket_create(AF_INET, SOCK_STREAM, SOL_TCP);//建立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伺服器寫入資料並讀取 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 $response; } //對發送的資料進行過濾 private function fliterSendData($contents){ //對寫入的資料進行處理 return $contents; } //所有錯誤資訊 public function getError(){ return $this->error; } //最後一次錯誤資訊 public function getLastError(){ return $this->error(count($this->error)); } //擷取最後一次發送的訊息 public function getLastMsg(){ return $this->queryStr; } public function getHost(){ return $this->host; } public function getPort(){ return $this->port; } //關閉socket串連 private function close(){ $this->socket&&socket_close($this->socket);//關閉串連 $this->socket=null;//串連資源初始化 } public function __destruct(){ $this->close(); } } 複製代碼

很簡單, socket, PHP
