What are some potential issues with using the "datetime-local" input type in PHP when handling dates from AJAX requests?

When using the "datetime-local" input type in HTML forms to gather date and time information, the format of the date and time may not be compatible with PHP's DateTime class. To solve this issue, you can convert the date and time string from the input field into a format that PHP can understand using the DateTime class.

// Retrieve the date and time string from the AJAX request
$dateString = $_POST['date'];

// Convert the date string into a DateTime object
$date = DateTime::createFromFormat('Y-m-d\TH:i', $dateString);

// Format the date object into a desired format
$formattedDate = $date->format('Y-m-d H:i:s');

// Use the formatted date as needed in your PHP code
echo "Formatted date: " . $formattedDate;
