本文实例讲述了php自定义类fsocket模拟post或get请求的方法。分享给大家供大家参考。具体如下：

zsocket.class.php文件如下：

<?phpclass ZSocket { /*  * Init  */ private function _fsockopen($host, $port, &$errno, &$errstr, $timeout){  $ip = @gethostbyname($host);  $s = @socket_create(AF_INET, SOCK_STREAM, 0);  if(socket_set_nonblock($s)){   $r = @socket_connect($s, $ip, $port);   if ($r || socket_last_error() == EINPROGRESS) {    $errno = EINPROGRESS;    return $s;   }  }  $errno = socket_last_error($s);  $errstr = socket_strerror($errno);  socket_close($s);  return false; } /*  * 设置Cookie */ private function _setCookie($cookie){  $_cookies = explode("; ",$cookie);  $_tmp = explode("=",$_cookies[0]);  setcookie($_tmp[0], $_tmp[1]);  return $_cookies; } /*  * 获取返回数据header内容 */ private function _getDataHeader(&$fp,&$reHeader,&$cookies){  $maxlen = 0;  while(!feof($fp)){   $line = fgets($fp,1024);   if(substr($line, 0, 12) == "Set-Cookie: "){ $cookies[] = $this->_setCookie(substr($line, 12)); }   $reHeader .= $line;   if(substr($line, 0, 16) == "Content-Length: "){    $maxlen = intval(substr($line, 16, -2));    }   if($line == "" || $line == "") break;  }  return $maxlen; } /*  * 获取返回数据正文内容 */ private function _getDataBody(&$fp,$maxlen){  $reData = "";  while(!feof($fp)){   $line = fgets($fp,$maxlen+1);   $reData .= $line;   if(strlen($line) < $maxlen) $maxlen = $maxlen - strlen($line);   else break;  }  return $reData; } /*  * 设置并返回要发送的header内容 */ public function get_HeaderInfo($host,$type="GET",$file="/",$params=array(),$head=array(),$cookies=array()){  $_params = $_cookies = "";  if(is_array($params)){   foreach($params as $key=>$value){     $_params .= "&".$key."=".urlencode($value);    }   $_params = (strlen($_params) > 1) ? substr($_params,1) : "";  }else if(is_string($params)){   $_params = urlencode($params);  }  foreach($cookies as $key=>$value){   $_cookies .= "; ".$key."=".urlencode($value);   }  $_cookies = (strlen($_cookies) > 2) ? substr($_cookies,2) : "";  $file .= ($type == "GET") ? ($_params == "" ? "" : "?".$_params) : "";  $header = $type." ".$file." HTTP/1.1";  $header .= "Host: ".$host."";  //$header .= "Referer: ".get_ip()."";  //$header .= "X-Forwarded-For: ".get_ip()."";  $header .= ($type == "GET") ? "" : "Content-Type: application/x-www-form-urlencoded";  if(is_array($head) && $head != array()){   foreach($head as $k=>$v){    $header .= $k.": ".$v."";   }  }  $header .= "Content-Length: ".strlen($_params)."";  if($_cookies != "") $header .= "Cookie: ".$_cookies."";  /*  foreach($_SERVER as $name => $value){   if(substr($name, 0, 5) == "HTTP_" && $name != "HTTP_HOST"){    $header .= str_replace(" ", "-", ucwords(strtolower(str_replace("_", " ", substr($name, 5))))).":".$value."";   }  }  */  $header .= "Connection: Close";  $header .= $_params."";  return $header; } /*  * 发送,并返回结果 Array */ public function get_SendData($host,$port=80,$header=""){  if(function_exists("fsockopen")){   $fp = fsockopen($host,$port,$errno,$errstr,10);  }else if(function_exists("pfsockopen")){   $fp = pfsockopen($host,$port,$errno,$errstr,10);  }else if(function_exists("stream_socket_client")){   $fp = stream_socket_client($host.":".$port,$errno,$errstr,10);  }else{   $fp = $this->_fsockopen($host,$port,$errno,$errstr,10);  }  $fp = fsockopen($host,$port,$errno,$errstr,10);  if(!$fp) return array("header"=>"","data"=>$errstr."--->".$errno,"cookie"=>"");  $reHeader = $reData = "";  $cookies = array();  fputs($fp,$header);  $maxlen = $this->_getDataHeader($fp,$reHeader,$cookies);  $reData = $this->_getDataBody($fp,$maxlen);  fclose($fp);  return array("header"=>$reHeader,"data"=>$reData,"cookie"=>$cookies); }}

demo代码如下：

$host = "www.yinxi.net";$port = "80";$type = "POST";$file = "/";$params = "";//include_once("include/zsocket.class.php"); //include$zsk = new ZSocket();$header = $zsk->get_HeaderInfo($host,$type,$file,$params);$data = $zsk->get_SendData($host,$port,$header);/*echo "<!--";print_r($header);print_r($data);echo "-->";*/var_dump($header);var_dump($data);

希望本文所述对大家的php程序设计有所帮助。
