PHP custom class fsocket simulates post or get request method_php tips

The example in this article describes the method of php custom class fsocket to simulate post or get requests. Share it with everyone for your reference. The details are as follows:

The zsocket.class.php file is as follows:

<&#63;php
class 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 == "\r\n" || $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) &#63; substr($_params,1) : '';
  }else if(is_string($params)){
   $_params = urlencode($params);
  }
  foreach($cookies as $key=>$value){
   $_cookies .= "; ".$key."=".urlencode($value); 
  }
  $_cookies = (strlen($_cookies) > 2) &#63; substr($_cookies,2) : '';
  $file .= ($type == 'GET') &#63; ($_params == '' &#63; '' : '&#63;'.$_params) : '';
  $header = $type." ".$file." HTTP/1.1\r\n";
  $header .= "Host: ".$host."\r\n";
  //$header .= "Referer: ".get_ip()."\r\n";
  //$header .= "X-Forwarded-For: ".get_ip()."\r\n";
  $header .= ($type == 'GET') &#63; '' : "Content-Type: application/x-www-form-urlencoded\r\n";
  if(is_array($head) && $head != array()){
   foreach($head as $k=>$v){
    $header .= $k.": ".$v."\r\n";
   }
  }
  $header .= "Content-Length: ".strlen($_params)."\r\n";
  if($_cookies != '') $header .= "Cookie: ".$_cookies."\r\n";
  /*
  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."\r\n";
   }
  }
  */
  $header .= "Connection: Close\r\n\r\n";
  $header .= $_params."\r\n";
  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);
 }
}

The demo code is as follows:

$host = 'www.jb51.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 "<!--\r\n";
print_r($header);
print_r($data);
echo "-->\r\n";
*/
var_dump($header);
var_dump($data);

I hope this article will be helpful to everyone’s PHP programming design.
