How can PHP beginners avoid common pitfalls when outputting content within functions?

Beginners can avoid common pitfalls when outputting content within functions by ensuring they properly use the `return` statement to return the content instead of directly echoing it within the function. This allows the function to be more versatile and reusable, as the output can be stored in a variable or used in different contexts. 

function generate_content() {
    $content = "This is the content to be outputted.";
    return $content;
}

echo generate_content();
