What best practices should be followed when modifying PHP code to display category-specific icons?

When modifying PHP code to display category-specific icons, it is best practice to use conditional statements to check the category and then display the corresponding icon. This can be achieved by utilizing an if-else or switch statement to determine the category and output the appropriate icon image based on the category. 

<?php
$category = "example_category";

if($category == "category1") {
    echo '<img src="category1_icon.png" alt="Category 1 Icon">';
} elseif($category == "category2") {
    echo '<img src="category2_icon.png" alt="Category 2 Icon">';
} elseif($category == "category3") {
    echo '<img src="category3_icon.png" alt="Category 3 Icon">';
} else {
    echo '<img src="default_icon.png" alt="Default Icon">';
}
?>
