DateTime: Syntax error, unexpected T_OBJECT_OPERATOR

Question

It works fine on localhost, but when I upload it to my host online it shows this error:

syntax error, unexpected T_OBJECT_OPERATOR

How can I fix it? Do I have to define the DateTime function somewhere?

if ((new DateTime($date))->diff(new DateTime())->days > 10) { 
    echo 'test';
}

UPDATE:

$date = DateTime::createFromFormat('y-M-d l H:i a', $date);
if ($date->diff(new DateTime())->days > 10) {

Answer 1

Class member access on instantiation was added in PHP 5.4. You are probably running PHP 5.3 so you cannot use that syntax.

Change:

if ((new DateTime($date))->diff(new DateTime())->days > 10) { 

to:

$date = new DateTime($date);
if ($date->diff(new DateTime())->days > 10) {
