php - Get the code of a page generated with JavaScript


I'm trying to get the code of an URL page after it JavaScript executed.
For the exemple :

    function getVideoURL($link){
        $data = file_get_contents($link);

    $link = htmlentities($_POST["link"]);


But this code give me the code of the url before javasript execution, is there a way to get it after javascript execution ?




file_get_contents get the original code of the page, it doesn't execute any client side code ( javascript )

To execute javascript you will need an entire browser emulation engine -- a headless browser.

use JonnyW\PhantomJs\Client;

function getVideoURL($link){
    $client = Client::getInstance();

    $request = $client->getMessageFactory()->createRequest($link, 'GET');

    $response = $client->getMessageFactory()->createResponse();

    $client->send($request, $response);

    if($response->getStatus() === 200) {

        // Dump the requested page content
        return $response->getContent();
    } else {
        return false;


$link = htmlentities($_POST["link"]);
