导读：这很有助于获得标题 $imageurl = "http://p.twimg.com/AW2-vIUCAAE_1FN.png"; $ch = curl_init(); curl_setopt ($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt ($ch,CURLOPT_URL,$image_url); curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,20); curl_setopt ($ch

这很有助于获得标题

$imageurl = "http://p.twimg.com/AW2-vIUCAAE_1FN.png";

  $ch = curl_init();
  curl_setopt ($ch,CURLOPT_RETURNTRANSFER,1);
  curl_setopt ($ch,CURLOPT_URL,$image_url);
  curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,20);
  curl_setopt ($ch,CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);
  curl_setopt ($ch,CURLOPT_FOLLOWLOCATION,true);
  curl_setopt($ch,CURLOPT_HEADER,true); 
  curl_setopt($ch,CURLOPT_NOBODY,true);

  $content = curl_exec ($ch);

  curl_close ($ch);

  print_r($content);

回国

回应Content-Type的最佳方式是什么？

试试这个：-

<?php
$image_url = "http://p.twimg.com/AW2-vIUCAAE_1FN.png";

  $ch = curl_init();
  curl_setopt ($ch,true);

  $content = curl_exec ($ch);
  $contentType = curl_getinfo($ch,CURLINFO_CONTENT_TYPE);
    echo $contentType;
    echo "<br/>";
  curl_close ($ch);
    echo "<pre>";
  print_r($content);
  ?>
