Because of PHP 8.2 deprecation, inf14428e4c0, we stopped converting non-ASCII characters to HTML entities. Instead, we started to explicitly insert `meta[charset]` tag at the start of the document. Later, we discovered that was breaking `html[lang]` so, inefbbc86df9, we made the insertion smarter. One of the improvements was that it would not insert the `meta[charset]` tag when it was already present. That, however, broke websites that had `title` tag before `meta[charset]`. On those, libxml2 would decode the `title` contents as ISO-8859-1. We could improve the logic (e.g. check that there is not text content before `meta[charset]`) or insert the tag unconditionally but it will probably be simplest to just go back to converting the non-ASCII characters to entities, just using non-deprecated function variant.
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);
