Question

How can I create a screenshot of a website using PHP and the GD library.

Answer 1

While you might be able to do something with imagegrabscreen or imagegrabwindow you'd only be able to use it on a Windows box, and even then it would be tricky.

You'd have to open a browser window to the specified url (you could do that with exec) and grab a screenshot using the aforementioned methods.

Here's an example from the manual entry for imagegrabwindow:

HWND;
$browser->Visible = true;
$browser->Navigate("http://www.libgd.org");

/* Still working? */
while ($browser->Busy) {
    com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");
imagedestroy($im);
?>
