$url="http://en.wikipedia.org/wiki/Pakistan";

  echo $ch;
  // used to spoof that coming from a real browser so we don't get blocked by some sites
  $useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";

  curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 4);
  curl_setopt($ch, CURLOPT_TIMEOUT, 8);
  curl_setopt($ch, CURLOPT_LOW_SPEED_TIME, 10);

  curl_close($ch);
?>

Answer 1

删除urlencode调用。

Answer 2

删除urlencode($url)应该是：

 $ch = curl_init($url);

Answer 3

Well.

If you remove urlencode() with instantiating your $ch -var, you go just fine. urlencode() is definitely wrong here.

Good:

 $ch = curl_init($url);

Bad:

 $ch = curl_init(urlencode($url));

Answer 4

$ch = curl_init($url);

代替

$ch = curl_init(urlencode($url));
