its possible but it will probably be more work than its worth.. You can send an AJAX request to your PHP server and then call a PHP function to read a webpage to string
$content = readfile("https://google.com/")
with google you can pass it search parameters in the URI string Example.
$content = readfile("https://www.google.com/#q=scirra")
From there you can parse the html code received and do what ever you want with it but you're in effect attempting to create a webcrawler and parsing HTML is a daunting task. I wish you luck in your journey.
