What are some common pitfalls when checking for correct dates in PHP scripts?

One common pitfall when checking for correct dates in PHP scripts is not using the correct date format or not handling invalid dates properly. To solve this, always use the correct date format and validate the date using PHP functions like `DateTime::createFromFormat()` or `strtotime()` before processing it. 

// Example of checking for correct date format and handling invalid dates

$dateString = '2022-13-45'; // Invalid date format

$date = DateTime::createFromFormat('Y-m-d', $dateString);

if ($date && $date->format('Y-m-d') === $dateString) {
    echo 'Valid date: ' . $date->format('Y-m-d');
} else {
    echo 'Invalid date format';
}
