Chrome Devtools Protocol PHP client

Build Latest Stable Version License

PHP client for Chrome Devtools Protocol.

Basic usage

// context creates deadline for operations
$ctx = Context::withTimeout(Context::background(), 30 /* seconds */);

// launcher starts chrome process ($instance)
$launcher = new Launcher();
$instance = $launcher->launch($ctx);

try {
	// work with new tab
	$tab = $instance->open($ctx);
	$tab->activate($ctx);

	$devtools = $tab->devtools();
	try {
		$devtools->page()->enable($ctx);
		$devtools->page()->navigate($ctx, NavigateRequest::builder()->setUrl("https://www.google.com/")->build());
		$devtools->page()->awaitLoadEventFired($ctx);

		// ... work with page ...
		// e.g.
		// - print to PDF: $devtools->page()->printToPDF($ctx, PrintToPDFRequest::make());
		// - capture screenshot: $devtools->page()->captureScreenshot($ctx, CaptureScreenshotRequest::builder()->setFormat("jpg")->setQuality(95)->build());

	} finally {
		// devtools client needs to be closed
		$devtools->close();
	}

} finally {
	// process needs to be killed
	$instance->close();
}

Headless Chrome isolated contexts

Headless Chrome supports feature called browser contexts - they're like incognito windows - cookies, local storage etc. are not shared. After browser context is destroyed, user data created in given context, are destroyed.

Unlike incognito windows, there can be multiple isolate browser contexts at the same time.

$ctx = Context::withTimeout(Context::background(), 10);
$launcher = new Launcher();
$instance = $launcher->launch($ctx);
try {
	$session = $instance->createSession($ctx);
	try {

		// $session implements DevtoolsClientInterface, same as returned from Tab::devtools()

	} finally {
		$session->close();
	}
} finally {
	$instance->close();
}
