Website crawling...

Hi,

This is my php script:

<?php
    header("Content-Type: text/plain");

    $context = stream_context_create(
    array(
        "http" => array(
            "header" => "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36"
            )
        )
    );
   
    $website = $_GET["URL"];

    $html = file_get_contents($website, false, $context);

    echo $html;
?>

PHP:

And I suppose the Javascript will pull the entire document with an AJAX call. The website I want to call will be a variable on the end of the script page.

For example

index.php?URL=http://www.google.com.au/

The HTML source code will then be echo'd out into the page. The ajax request will pull that page. How can I do this asynchronously so that the php script has enough time to render the entire HTML source code before the AJAX pulls in the page?
