GrabzIt has just launched their screenshot service, which allows developers to easily take screenshots of websites for free using the open source GrabzIt PHP Library. To take a screenshot with GrabzIt you first need to register to get your application key and secret, once done you will be up and running in no time.

 

You first request a screenshot with the following code:

 

include("GrabzItClient.class.php");

//Create the GrabzItClient class
//Replace "APPLICATION KEY", "APPLICATION SECRET" with the values from your account!
$grabzIt = new GrabzItClient("APPLICATION KEY", "APPLICATION SECRET");
//Take the picture the method will return the unique identifier assigned to this task
$id = $grabzIt->TakePicture("http://www.google.com", "http://www.example.com/GrabzItHandler.php");

 

Then you accept the resulting screenshot with code similar to this:

 

include("GrabzItClient.class.php");

$message = $_GET["message"];
$customId = $_GET["customid"];
$id = $_GET["id"];
$filename = $_GET["filename"];

//Custom id can be used to store user ids or whatever is needed for the later processing of the
//resulting screenshot

$grabzIt = new GrabzItClient("APPLICATION KEY", "APPLICATION SECRET");
$result = $grabzIt->GetPicture($id);

if (!$result)
{
	return;
}

//Ensure that the application has the correct rights for this directory.
file_put_contents("images" . DIRECTORY_SEPARATOR . $filename, $result);

 

Remember to replace APPLICATION KEY and APPLICATION SECRET with your actual values.
