这是我的密码:

<?php
require 'lib/Readability.inc.php'; 

$source = 'http://techcrunch.com/2011/04/02/conduit-acquires-web-application-platform-wibiya-for-45-million-sources/';

$Readability = new Readability($source, $html_input_charset);  //default charset is utf-8 
$ReadabilityData = $Readability->getContent(); 
$title = $ReadabilityData['title'];
$content = $ReadabilityData['content'];
?>
<html>
<head>
    <title>test - <?php echo $title; ?></title>
</head>
<body>
<?php
echo "<h1>". $title."</h1> "; 
echo $content;
?>
</body>
</html>

这是我得到的输出:

<html>
<head>
<title>test - </title>

我正在寻找的输出如下所示:

您应该向它提供一个html文档

$source = 'http://techcrunch.com/2011/04/02/conduit-acquires-web-application-platform-wibiya-for-45-million-sources/';

$html = file_get_contents($source);    
$Readability = new Readability($html, $html_input_charset);
