What is the potential issue with using strtotime in PHP 8.1 with null values?

Using strtotime with null values in PHP 8.1 can result in a warning because null is not a valid parameter for the strtotime function. To solve this issue, you can check if the value is null before passing it to strtotime or provide a default value if it is null. 

$date = null;

if ($date !== null) {
    $timestamp = strtotime($date);
} else {
    $timestamp = time(); // Default to current timestamp
}

echo $timestamp;
