$browserFactory = new BrowserFactory("/Applications/Chromium.app/Contents/MacOS/chromium");
$browser = $browserFactory->createBrowser(['noSandbox' => $sandBox,
'headless' => true,
'connectionDelay' => 0.8,
'debugLogger'=> 'php://stdout']);
$page = $browser->createPage();
$page->navigate($url)->waitForReload();
$browser->close();
2, browser screenshots
$browserFactory = new BrowserFactory("/Applications/Chromium.app/Contents/MacOS/chromium");
$browser = $browserFactory->createBrowser(['noSandbox' => $sandBox,

IF ($ SleepTime) {
SLEEP (. 6); // wait 6S resource loading and rendering is complete, the script processing need to wait for a general asynchronous
}
$ x = 10; $ y = 10; // from the X, Y margins
$ width = 100; $ height = 100; // screenshot width and height
$ clip = new Clip ($ x , $ y, $ width, height $);
$ Screenshot = $ page-> Screenshot ([

'marginLeft' => 5.0, // defaults to ~0.4 (must be float, value in inches)
'marginRight' => 1.0 // defaults to ~0.4 (must be float, value in inches)
];
$pdf = $page->pdf($options);
// save the file address
$ pdf-> saveToFile ($ outputImgFullPath) ;
Fourth, the load js:
$page->addScriptTag([
'url' => 'https://code.jquery.com/jquery-3.3.1.min.js'

$ Page-> evaluate ( '. $ ( ". My.element") html ()'); // calculate the text lines on a given page string
