What is the best practice for displaying selected values from a form in PHP?

When displaying selected values from a form in PHP, it is best practice to use the ternary operator to check if a value is selected and then display it accordingly. This helps to ensure that only selected values are displayed and prevents errors from displaying incorrect values. 

<?php
// Assuming form values are stored in variables
$option1 = 'Option 1';
$option2 = 'Option 2';
$option3 = 'Option 3';

// Check if each option is selected and display it
echo ($selectedOption == $option1) ? 'selected' : '';
echo ($selectedOption == $option2) ? 'selected' : '';
echo ($selectedOption == $option3) ? 'selected' : '';
?>
