Why is it recommended to retrieve dates from the database in ISO format in PHP?

Retrieving dates from the database in ISO format in PHP is recommended because it ensures consistency in date formatting across different systems and platforms. ISO format (YYYY-MM-DD) is also easily readable and sortable, making it ideal for storing and manipulating dates in PHP. 

// Retrieve date from the database in ISO format
$dateFromDB = '2022-01-15';

// Convert the date to a PHP DateTime object
$date = new DateTime($dateFromDB);

// Format the date in ISO format
$formattedDate = $date->format('Y-m-d');

echo $formattedDate; // Output: 2022-01-15
