README

Headless Chrome is shipping in Chrome 59. It's a way to run the Chrome browser in a headless environment. Essentially, running Chrome without chrome! It brings all modern web platform features provided by Chromium and the Blink rendering engine to the command line.

PHPHeadlessChrome provides a simple usage helper class to create PDF and / or screenshots using a Headless Chrome instance. Trigger PDF / Screenshots generation for webpages / string HTML or local URL.

In order to use this PHPHeadlessChrome helper make sure Google Chrome is correctly installer from version 59 or onwards.

Installation

Install the package through composer:

composer require daandesmedt/phpheadlesschrome

Make sure, that you include the composer autoloader somewhere in your codebase.

Usage

Use the PHPHeadlessChrome tool when you want to convert a webpage / HTML text or (local) HTML file to a PDF or image screenshot.
