php curl CURLOPT_HEADER 和 DOM

Question

我有以下代碼：

curl_setopt($ch, CURLOPT_URL, $host);
  curl_setopt($ch, CURLOPT_HEADER, 1); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  $html = curl_exec($ch);


  preg_match_all('|Set-Cookie: (.*);|U', $html, $results);  
  $cookies = implode(';', $results[1]);


  $dom = new DOMDocument();
  $dom->loadHTML($html);

在線$dom->loadHTML($html); 我收到以下錯誤：

Warning: DOMDocument::loadHTML() [function.DOMDocument-loadHTML]:
Misplaced DOCTYPE declaration in
Entity, line: 12 in
D:\Programs\xampp\xampp\htdocs\ip\megafonmoscow.php

是線curl_setopt($ch, CURLOPT_HEADER, 1); 這個錯誤的原因？ 因為餅干，我需要它。 關於如何解決這個問題的任何想法？

Answer 1

mck89 方法的替代方法是將標題和正文下載在一起，但在嘗試解析它之前將它們拆分：

$html = curl_exec($ch);

[snip]

$html = preg_replace('/^.*\n\n/s','',$html,1); // strip out everything before & including the double line break between headers and body

$dom = new DOMDocument();
$dom->loadHTML($html);

這節省了 HTTP 請求，因此節省了一定的時間。

Answer 2

嘗試刪除該行，以便它不會返回標頭，然后在 curl 請求之后使用get_headers函數獲取它們。

  curl_setopt($ch, CURLOPT_URL, $host);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  $html = curl_exec($ch);
  $headers=get_headers($host, 1);
