What are the potential pitfalls of using echo and print within PHP functions, as discussed in this forum thread?

Using echo and print within PHP functions can lead to unexpected behavior, as they directly output content to the browser instead of returning it as a value. This can make it difficult to manipulate or store the output within the function. To solve this issue, it's recommended to use return statements to return the desired output from the function instead of using echo or print.

function myFunction() {
    $output = "Hello, World!";
    return $output;
}

// Call the function and store the output in a variable
$result = myFunction();

// Output the result
echo $result;
