Check that string is valid date

Question

How can I check that my string is a valid date ("2018-01-01").

Is there a simple way, or do I need to do something like this:

if (Carbon::createFromFormat('YOUR DATE FORMAT', $stringVariable) !== false) {
    // valid date
}

Answer 1

$timestamp  = strtotime($date);

return $timestamp ? $date  : null ;
