How can PHP developers ensure that user input for date and time is accurate and follows the correct format?

To ensure that user input for date and time is accurate and follows the correct format, PHP developers can use PHP's built-in functions like strtotime() or DateTime::createFromFormat() to parse and validate the input. They can also use regular expressions to enforce a specific date and time format. Additionally, developers can provide clear instructions and examples for users to input dates and times correctly. 

// Example code snippet to validate user input for date and time
$user_input = $_POST['date_time'];

// Validate date and time format using DateTime::createFromFormat()
$date_time = DateTime::createFromFormat('Y-m-d H:i:s', $user_input);
if ($date_time === false) {
    echo "Invalid date and time format. Please enter in the format 'YYYY-MM-DD HH:MM:SS'.";
} else {
    echo "Date and time input is valid.";
}
