PhpPupeeteer based on Puppeteer. A Puppeteer bridge for PHP, supporting the entire API. Based on Rialto, a package to manage Node resources from PHP.

Here are some examples borrowed from Puppeteer's documentation and adapted to PHP's syntax:

Example - navigating to https://example.com and saving a screenshot as example.png:

use PhpPupeeteer\PhpPupeeteer;

$phpPuppeteer = new PhpPupeeteer;
$browser = $phpPuppeteer->getBrowser([
    'args' => [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--disable-gpu',
        '--incognito',
    ],
]);
$page = $browser->newPage();
$page->gotoWithWait('https://example.com');
$page->screenshot(['path' => 'example.png']);
$browser->close();

Example - show browser window

use PhpPupeeteer\PhpPupeeteer;

$phpPuppeteer = new PhpPupeeteer;
$browser = $phpPuppeteer->getBrowser([
    'headless' => false,
    'args' => [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--incognito',
        '--start-maximized',
    ],
]);
$page = $browser->newPage();
$page->gotoWithWait('https://example.com');
$page->screenshot(['path' => 'example.png']);
$browser->close();

Example - evaluate a script in the context of the page:

use Puphpeteer\Puppeteer;
use Puphpeteer\Data\Js;

$puppeteer = new PhpPupeeteer;

$browser = $phpPuppeteer->getBrowser();
$page = $browser->newPage();
$page->gotoWithWait('https://example.com');

// Get the "viewport" of the page, as reported by the page.
$dimensions = $page->evaluate(Js::createWithBody("
    return {
        width: document.documentElement.clientWidth,
        height: document.documentElement.clientHeight,
        deviceScaleFactor: window.devicePixelRatio,
    };
"));

printf('Dimensions: %s', print_r($dimensions, true));

$browser->close();

Requirements and installation

This package requires PHP >= 7.1 and Node >= 8.

Install it with these two command lines:

composer require aktuba/php-puppeteer
npm install @nesk/puphpeteer

Notable differences between PhpPupeeteer and Puppeteer

Puppeteer's class must be instanciated

Instead of requiring Puppeteer:

const puppeteer = require('puppeteer');

You have to instanciate the PhpPupeeteer class:

use PhpPupeeteer\PhpPupeeteer;

$puppeteer = PhpPupeeteer;

This will create a new Node process controlled by PHP.

You can also pass some options to the constructor, see Rialto's documentation. PuPHPeteer also extends these options:

[
    // Logs the output of Browser's console methods (console.log, console.debug, etc...) to the PHP logger
    'log_browser_console' => false,
]

$phpPuppeteer = $phpPuppeteer->getBrowser([
	'read_timeout' => 65, // In seconds
]);

$browser->newPage()->goto($url, [
    'timeout' => 60000, // In milliseconds
]);

No need to use the await keyword

With PhpPupeeteer, every method call or property getting/setting is synchronous.

Some methods have been aliased

The following methods have been aliased because PHP doesn't support the $ character in method names:

• $ => querySelector
• $$ => querySelectorAll
• $x => querySelectorXPath
• $eval => querySelectorEval
• $$eval => querySelectorAllEval

Use these aliases just like you would have used the original methods:

$divs = $page->querySelectorAll('div');

Evaluated functions must be created with \PhpPupeeteer\Data\Js

Functions evaluated in the context of the page must be written with the JsFunction class, the body of these functions must be written in JavaScript instead of PHP.

use PhpPupeeteer\Data\Js;

$pageFunction = Js::createWithParameters(['element'])
    ->body("return element.textContent")
;

Exceptions must be catched with ->tryCatch

If an error occurs in Node, a Node\FatalException will be thrown and the process closed, you will have to create a new instance of Puppeteer.

To avoid that, you can ask Node to catch these errors by prepending your instruction with ->tryCatch:

use Nesk\Rialto\Exceptions\Node;

try {
    $page->tryCatch->goto('invalid_url');
} catch (Node\Exception $exception) {
    // Handle the exception...
}

Instead, a Node\Exception will be thrown, the Node process will stay alive and usable.
