What are the best practices for organizing and structuring PHP code to avoid issues like character evaluation in category checks?

Issue: When checking categories in PHP code, it is important to avoid issues with character evaluation by using strict comparison operators (===) instead of loose comparison operators (==). This ensures that both the value and the type of the variables are checked, preventing unexpected results. Example fix: 

$category = "1";
if ($category === "1") {
    echo "Category 1 selected";
} else {
    echo "Category not selected";
}
