使用PHP實現 GET,POST 資料

1. 使用 PHP 獲得網頁內容 GET方式<?phpfunction 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($fp); } return true;}?>2. 使用 PHP 向頁面 POST 資料<?phpfunction socketPost($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($fp); } return true;}?>如果post報錯，把$out .= "Connection: Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
