How can PHP beginners ensure they are using the correct date and time functions when working with databases?

When working with databases in PHP, beginners can ensure they are using the correct date and time functions by using the built-in functions provided by PHP, such as date() and strtotime(). It is important to properly format dates and times before storing or retrieving them from the database to avoid any issues with data consistency.

// Example of using the date() function to format the current date
$currentDate = date('Y-m-d H:i:s');

// Example of using the strtotime() function to convert a date string to a Unix timestamp
$dateString = '2022-12-31';
$timestamp = strtotime($dateString);
