如果现在时间超过上次更新后的3小时

Question

I need to have a validation that checks if the "last_update" is done before 3 hours or less.

I have this PHP code:

if($user['last_update'] < strtotime("3 hours")) {
    $msg .= "You can only register every 3 hour.";
}

How could this be done?

Answer 1

If $user['last_update'] is in date format, then

if (time() - strtotime($user['last_update']) < 3 * 3600) {
  //..
}
