Transport Central

To setup Transport Central for yourself, you need to create a HTML file (use this as a starting point) with the stop IDs for the stops you use. You can get the stop IDs from NextBusBristol. Get the stop ID which I've helpfully highlighted in red.

Create a h2, div and table for each stop. Replace [STOPID] with the stop ID if that isn't obvious.

STOP NAME ←

You also need to use this PHP script that proxies the request to NextBusBristol and turns HTML into JSON for easy parsing by your phone browser.

			$data4json[] = array( 'number' => $matches[1][$i], 'destination' => $matches[2][$i], 'waittime' => $matches[3][$i] );
		}


	 	return json_encode($data4json);
	}
}

header('Content-type: application/json');

$transport = new Transport();

if (array_key_exists('stop', $_GET)) {
	echo $transport->fetchStop($_GET['stop']);
}

It's not the most advanced thing in the world but handy when you are waiting at a bus stop.
