Web Scraping in CI4

You can easily use and integrate PHP libraries like

https://github.com/voku/simple_html_dom
https://github.com/spekulatius/PHPScraper

in CodeIgniter. Simply create a library.

PHP Code:

namespace App\Libraries;

use simplehtmldom\HtmlWeb;

class HtmlDomParser
{
    public function parseFromUrl($url)
    {
        $htmlWeb = new HtmlWeb();
        $html = $htmlWeb->load($url);

        return $html;
    }
}
