Answer 1

index.php is returning wrong data, if you look closer then you will see it is trying to send success = false result as json data but probably for testing purposes, it is also returning array content directly before the json data.
Besides, if this is supposed to be a json result then you need to use json_decode before using the returned json object as a class object like $json->order_id.
This is what I get when I try your current URL With the parameters you provided: Look at the last line:
Array
(
[0] => Array
(
[order_id] => 6
[name] => zoraya panansar
[status] => Complete
[date_added] => 2014-01-24 23:06:09
[products] => 4
[total] => 14.8000
[address_1] => 345 goldhawk road
[address_2] => hammersmith
[city] => london
[Postcode] => w6 0wz
[Country] => United Kingdom
[Email] => zpanansar#yahoo.com
[Tele.] => 0786870150
)
[1] => Array
(
[order_id] => 5
[name] => ciria ann nuqui
[status] => Complete
[date_added] => 2014-01-24 17:58:36
[products] => 7
[total] => 36.4000
[address_1] => 345 goldhawk road
[address_2] => hammersmith

{"success":false}

You can not access the data that the server is returning. Instead of returning you a json object, the server is returning you the print_r() output over an array.
If its your server, then stop the print, and use json_encode() over the array before printing.
If it's not your server, then you have to parse the values from the text. You can use preg_match_all() for this.
preg_match_all("/\[order_id\] => ([^\n\r]+)/", $json, $m);
print_r($m[1]);
There may be built-in php function that can take such print_r() output and revert back into a php array, but I don't know about it!

Change the response from the url to json (Use json_encode function)
The last Row in url script should be
echo json_encode($some_array);
And than if you want the content:
$array = json_decode(file_get_contents($url),TRUE);
if(!is_array($array)){
echo 'bad response';
exit();
}
var_dump($array);
echo $array[0]['order_id'];
