How can PHP code be optimized to prevent all banners of every type from being displayed when only one type is selected?

To optimize PHP code to prevent all banners of every type from being displayed when only one type is selected, you can use conditional statements to check the selected type and only display the corresponding banner. This can be achieved by using if-else or switch statements to determine which banner to display based on the selected type. 

<?php
// Assuming $selectedType contains the selected banner type

if($selectedType == 'type1') {
    // Display banner for type 1
    echo '<img src="banner_type1.jpg">';
} elseif($selectedType == 'type2') {
    // Display banner for type 2
    echo '<img src="banner_type2.jpg">';
} elseif($selectedType == 'type3') {
    // Display banner for type 3
    echo '<img src="banner_type3.jpg">';
} else {
    // Default banner if no type is selected
    echo '<img src="default_banner.jpg">';
}
?>
