来自 file_get_contents 的奇怪结果

Question

<?php

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

?>

为什么returns这个？

如果我用 http://google.com 替换 URL 一切似乎都很好。

Answer 1

服务器正在返回内容gzip:ed。

因此您需要 gunzip 它才能阅读。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);
