How can one properly format and display dates in PHP?

When displaying dates in PHP, it is important to properly format them to ensure they are easily readable and consistent. This can be achieved using the date() function in PHP, which allows you to specify the desired format for the date output. By providing the appropriate format string to the date() function, you can display dates in various formats such as "Y-m-d" for year-month-day or "d/m/Y" for day-month-year.

// Example of formatting and displaying a date in PHP
$date = "2022-05-15";
$formatted_date = date("Y-m-d", strtotime($date));
echo $formatted_date;
