What are the potential pitfalls of displaying dates in different formats in PHP and storing them in a database?

When displaying dates in different formats in PHP and storing them in a database, the potential pitfalls include inconsistencies in date interpretation and manipulation. To avoid these issues, it is recommended to store dates in a standardized format (such as YYYY-MM-DD) in the database and then format them accordingly for display in PHP.

// Storing dates in a standardized format in the database
$date = date('Y-m-d', strtotime($inputDate));

// Displaying dates in a specific format in PHP
$formattedDate = date('d/m/Y', strtotime($date));
echo $formattedDate;
