This question already has an answer here:
How would I change the date 18/08/2018 10:46:15 pm to Sat 25, 10:46:15 pm in PHP. I am doing the following:
```
$OldDate = "18/08/2018 10:46:15 pm";
$NewDate = $OldDate->format(D-j, Y-H:I:S);
echo $NewDate;
?>```
However, it is not showing anything, am I formatting it correctly?

Your old date is just a string. If you want to format it, you need to create a DateTime object using that string the constructor.
You're also incorrectly specifying the format
$OldDate = new DateTime("18/08/2018 10:46:15 pm");
echo $OldDate->format("L-j, h:i:s A");
