How can PHP developers ensure that date formats are correctly handled when retrieving data from a MySQL database and displaying them in input fields?

When retrieving dates from a MySQL database and displaying them in input fields, PHP developers should ensure that the date format is correctly handled to avoid any formatting issues. One way to do this is by using the `date()` function in PHP to format the date retrieved from the database before displaying it in the input field.

// Retrieve date from MySQL database
$dateFromDatabase = $row['date'];

// Format the date using the date() function
$formattedDate = date('Y-m-d', strtotime($dateFromDatabase));

// Display the formatted date in an input field
echo '<input type="text" name="date" value="' . $formattedDate . '">';
