What are the potential pitfalls of using incorrect date formats in PHP when retrieving dates from a MySQL database?

Using incorrect date formats when retrieving dates from a MySQL database in PHP can lead to errors or unexpected results in your application. To avoid this issue, ensure that the date format used in your PHP code matches the format stored in the database. You can use the date() function in PHP to format dates retrieved from the database into the desired format.

// Retrieve date from MySQL database
$dateFromDB = "2022-01-15";

// Format date using date() function
$formattedDate = date("Y-m-d", strtotime($dateFromDB));

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