How can the PHP code snippet be optimized to improve readability and functionality?

The PHP code snippet can be optimized by using meaningful variable names, breaking down complex logic into smaller, more manageable functions, and adding comments to explain the purpose of each section of code. This will improve readability and maintainability of the code. 

<?php

// Define meaningful variable names
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];

// Break down complex logic into smaller functions
function get_full_name($first_name, $last_name) {
    return $first_name . ' ' . $last_name;
}

// Add comments to explain the purpose of each section of code
$full_name = get_full_name($first_name, $last_name);
echo 'Full Name: ' . $full_name;

?>
