Question

所以我尝试废弃这个URL：xxxx.fr和cURL，但无法访问页面HTML代码，标题和正文都是空的。 HTTP代码返回为200 我尝试使用其他网址（不同的域名），它就像一个魅力。我也尝试使用不同的User Agent和Referer

你知道什么是错的吗？至少可以有人在您自己的服务器上尝试此代码，如果您遇到同样的问题，请告诉我们吗？

谢谢

以下是我的代码：

  $url = 'http://www.xxxx.fr';

  $header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
  $header[] = "Cache-Control: max-age=0";
  $header[] = "Connection: keep-alive";
  $header[] = "Keep-Alive: timeout=5, max=100";
  $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
  $header[] = "Accept-Language: en-us,en;q=0.5";
  $header[] = ""; // BROWSERS USUALLY LEAVE BLANK

  $curl = curl_init ();
  curl_setopt($curl, CURLOPT_URL, $url);
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
  curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0");
  curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate');
  curl_setopt($curl, CURLOPT_REFERER, "http://www.google.fr");
  curl_setopt($curl, CURLOPT_HEADER, 1);
  curl_setopt($curl, CURLINFO_HEADER_OUT, 1);
  curl_setopt($curl, CURLOPT_VERBOSE, 1);
  curl_setopt($curl, CURLOPT_COOKIEFILE, getcwd().'/cookies.txt');
  curl_setopt($curl, CURLOPT_COOKIEJAR, getcwd().'/cookies.txt');
  curl_setopt($curl, CURLOPT_TIMEOUT, 30);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
  $curlData = curl_exec($curl);

  $infos = curl_getinfo($curl);
  print_r($infos);

  curl_close ( $curl );

  echo "<hr>Page:<br />";
  echo htmlentities($curlData);

这是print_r（$ infos）的结果：

// EDIT

htmlentities（$ curlData）返回空字符串，因为source的编码是非UTF-8字符串see this link

应该有效：

 htmlentities($curlData, ENT_QUOTES,'ISO-8859-1' );

在PHP 5.4版本中，htmlspecialchars（）不使用ISO-8859-1作为默认编码。事实上，PHP 5.4中的htmlspecialchars（）使用UTF-8。您可能期望，htmlspecialchars（）只会跳过非UTF-8字节序列或将它们转换为“未找到”字符。事实上，htmlspecialchars（）返回一个空字符串：没有生成错误，没有返回错误代码，也没有引发异常，如果传入无效的UTF-8序列，只返回一个空字符串

尽管HTTP Code 200，PHP cURL返回空标题和正文
