Backlink Validator for PHP

A PHP package for developers who need to validate backlinks. Unlike tools that scan the internet or analyze Google search results to find backlinks, it checks a predefined list of backlinks on remote pages to confirm that they exist and are correct. Two scraping modes are offered: a simple engine and a Chromium based engine that handles JavaScript. Installation takes three steps: adding the package through Composer, installing Chromium and using the autoloader, followed by usage examples. It is useful for anyone who has bought, earned or been promised links and wants to confirm they are still live. Written in PHP and released under the GPL-3.0 license, so it is free to use. The package reports whether each expected link is present and correct, which saves a manual visit to every linking page.
