Test my free and online Keyword Density Checker
This library provides PHP functions to extract keywords from HTML and text. Read PHP DOC
Install package with composer
composer require hugsbrugs/php-keywords
In your PHP code, load librairy
require_once __DIR__ . '/vendor/autoload.php';
use Hug\Keywords\Keywords as Keywords;If you have HTML as input, first extract text from HTML (it also returns Title and meta description)
$text = Keywords::get_text_from_html($html);Then call the Keyword class with text as only required parameter. In this case the library patrickschur/language-detection will be used to automatically detect language.
$Keywords = new Keywords($text);
$kws = $Keywords->keywords;If you know which language is used in your text, then pass parameter lang as second argument. It will allow to load stop words list from voku/stop-words library. Supported languages codes by this library are : ar, bg, ca, cz, da, de, el, en, eo, es, et, fi, fr, hi, hr, hu, id, it, ka, lt, lv, nl, no, pl, pt, ro, ru, sk, sv, tr, uk, vi.
$Keywords = new Keywords($text, $lang);
$kws = $Keywords->keywords;If your language is not supported by voku/stop-words library or if you want to use your own stop words list, set 2nd argument as null and pass your own stop words array as 3rd argument.
$Keywords = new Keywords($text, 'auto', ['my custom stop word array']);
$kws = $Keywords->keywords;You can optionnaly pass a 4th argument as the max numbers of keywords to be returned. Set to 20 by default. Pass 0 if you want all keywords. In all cases it only returns keywords with occurence above 1.
$Keywords = new Keywords($text, 'fr', [], 10);
$kws = $Keywords->keywords;You can also pass an optionnal 5th argument array containing a list of chars you want to be removed from the analysed text. The default list is : | / & : , ; ! ? _ * - - ... → – « » + ✔ # ¿ < > [ ] { }
$Keywords = new Keywords($text, 'fr', [], 10, ['my custom chars list']);
$kws = $Keywords->keywords;The optionnal 6th argument represents minimum keyword occurence to be returned. Default value is set to 2 so only keywords with minimum 2 occurences will be returned. If you want to get all keywords including those with only 1 occurence, set this parameter to 1.
$Keywords = new Keywords($text, 'fr', [], 10, ['my custom chars list'], 1);
$kws = $Keywords->keywords;For the url https://naturo-paca.fr/definition-naturopathie, the library outputs :
