Answer 1

服务器正在返回内容gzip：ed。

Screenshot from inspector

因此，您需要gunzip才能阅读它。一种方法是使用Zlib函数：

$zd = gzopen('http://www.inc.com/patricia-fletcher/how-to-avoid-the-most-common-start-up-marketing-mistakes.html', "r");
$contents = gzread($zd, 100000);
gzclose($zd);

echo $contents;

输出：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en" xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml">

Answer 2

响应是gzip压缩的，使用gzdecode()。

$c = file_get_contents( 'http://www.inc.com/patricia-fletcher/how-to-avoid-the-most-common-start-up-marketing-mistakes.html' );
echo gzdecode($c);

来自file_get_contents的奇怪结果
