How can live coding sessions be optimized to cater to both beginners and advanced PHP developers effectively?

To optimize live coding sessions for both beginners and advanced PHP developers, it is essential to provide clear explanations of each step, use comments to explain complex concepts, and offer additional resources for further learning. Additionally, incorporating a mix of basic and advanced topics in the coding session can cater to the varying skill levels of participants effectively.

// Example code snippet demonstrating a mix of basic and advanced PHP concepts
<?php

// Basic PHP code for beginners
$name = "John";
echo "Hello, $name!";

// Advanced PHP code for experienced developers
function factorial($n) {
    if ($n <= 1) {
        return 1;
    } else {
        return $n * factorial($n - 1);
    }
}

echo "Factorial of 5 is: " . factorial(5);

?>
