1.使用PHP获得网页内容GET方式<?phpfunctionsocketGet($url,&$ret){ $urlArr=parse_url($url); $hos

1. 使用 PHP 获得网页内容 GET方式


<?php
function socketGet($url, &$ret)
{
 $urlArr = parse_url($url);
 $host = $urlArr['host'];
 $port = isset($urlArr['port'])?$urlArr['port']:80;
 $path = isset($urlArr['path'])?$urlArr['path']:"/";
 $fp = fsockopen($host, $port, $errno, $errstr, 30);
 if (!$fp)
 {
  echo "$errstr ($errno)<br />\n";
  return false;
 }
 else
 {
     $out = "GET $path HTTP/1.1\r\n";
     $out .= "Host: $host\r\n";
     $out .= "Connection: Close\r\n\r\n";
  $ret = "";
     fwrite($fp, $out);
     while (!feof($fp))
  {
         $ret .= fgets($fp, 128);
     }
     fclose($fp);
 }
 return true;
}
?>

2. 使用 PHP 向页面 POST 数据


<?php
function socketPost($url, $data, &$ret)
{
 $urlArr = parse_url($url);
 $host = $urlArr['host'];
 $port = isset($urlArr['port'])?$urlArr['port']:80;
 $path = isset($urlArr['path'])?$urlArr['path']:"/";
 $fp = fsockopen($host, $port, $errno, $errstr, 30);
 if (!$fp)
 {
     echo "$errstr ($errno)<br />\n";
  return false;
 }
 else
 {
     $out = "POST $path HTTP/1.1\r\n";
     $out .= "Host: $host\r\n";
  $out .= "Content-Type: application/x-www-form-urlencoded\r\n";
  $out .= "Content-Length: ".strlen($data)."\r\n";
     $out .= "Connection: Keep-Alive\r\n\r\n";
  $out .= $data;
  $ret = "";
     fwrite($fp, $out);
     while (!feof($fp))
  {
         $ret .= fgets($fp, 128);
     }
     fclose($fp);
 }
 return true;
}
?>
如果post报错,把$out .= "Connection: Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
