This is deprecated since PHP 8.2:
Deprecated: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead
It was used because `DOMDocument`, which uses libxml2 internally, will parse the HTML as ISO-8859-1, unless the document contains an XML encoding declaration or HTML meta tag setting character set.
Since first such element wins, putting the `meta[charset]` up front will ensure the parser uses the correct encoding, even if the document contains incorrect meta tag (e.g. when the document is converted to UTF-8 without also updating the metadata by the software passing it to Readability).

Readability
This is an extract of the Readability class from this full-text-rss fork. It can be defined as a better version of the original php-readability.
Differences
The default php-readability lib is really old and needs to be improved. I found a great fork of full-text-rss from @Dither which improve the Readability class.
- I've extracted the class from its fork to be able to use it out of the box
- I've added some simple tests
- and changed the CS, run
php-cs-fixerand added a namespace
But the code is still really hard to understand / read ...
Requirements
By default, this lib will use the Tidy extension if it's available. Tidy is only used to cleanup the given HTML and avoid problems with bad HTML structure, etc .. It'll be suggested by Composer.
Also, if you got problem from parsing a content without Tidy installed, please install it and try again.
Usage
use Readability\Readability;
$url = 'http://www.medialens.org/index.php/alerts/alert-archive/alerts-2013/729-thatcher.html';
// you can use whatever you want to retrieve the html content (Guzzle, Buzz, cURL ...)
$html = file_get_contents($url);
$readability = new Readability($html, $url);
// or without Tidy
// $readability = new Readability($html, $url, 'libxml', false);
$result = $readability->init();
if ($result) {
// display the title of the page
echo $readability->getTitle()->textContent;
// display the *readability* content
echo $readability->getContent()->textContent;
} else {
echo 'Looks like we couldn\'t find the content. :(';
}
If you want to debug it, or check what's going on, you can inject a logger (which must follow Psr\Log\LoggerInterface, Monolog for example):
use Readability\Readability;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
$url = 'http://www.medialens.org/index.php/alerts/alert-archive/alerts-2013/729-thatcher.html';
$html = file_get_contents($url);
$logger = new Logger('readability');
$logger->pushHandler(new StreamHandler('path/to/your.log', Logger::DEBUG));
$readability = new Readability($html, $url);
$readability->setLogger($logger);
