In web development and coding, there is always more than one way to get things done.
You don't need to reinvent the wheel though you can always improve on existing solutions. That is what everybody does.

Straight to the Post, assuming you want to award points to your users every day, you can either do it at a particular time of each day or simply use the duration of 24 hours to perform the Award task.

STEP BY STEP

Create 2 Columns

1. Used to store the state of whether user have been awarded point ever before. I named it "awarded_at_all"
2. Used To store the time duration for the day i.e 24 hours duration(60*60*24) = 86400 seconds. I named it next_5

The implication of the below code is that, no matter the number of times it runs, if the conditions are not, the task will never run.
If you have any questions, ask in the comment section. Cheers.

The PHP Code:


function dailyPoint($db)
{
if(isset($_COOKIE['token23'])){
$token = $_COOKIE['token23'];
$ddd = returnUserDetails($db, $token);

if($ddd != null){
$userId = $ddd['uid'];
$atAll = $ddd['at_all'];
$nextTime = $ddd['next_time'];
$currentTime = time();
$next24 = $currentTime + (24*60*60);
if($atAll == null){
$db->query("update ur34 set awarded_at_all= '1', next_5 = '$next24' where usa45 = '$userId' limit 1");
addPoint($db, 7, $userId);
}
else if($currentTime>=$nextTime){
$db->query("update ur34 set next_5 = '$next24' where usa45 = '$userId' limit 1");
addPoint($db, 7, $userId);
}
return $ddd;
}return null;

}return null;
}
