How can PHP code be structured to avoid errors and confusion?

To avoid errors and confusion in PHP code, it is important to follow best practices such as using meaningful variable names, commenting code effectively, organizing code into logical sections, and using proper indentation and formatting. By structuring your code in a clear and organized manner, you can make it easier to read, understand, and maintain. 

<?php

// Example of well-structured PHP code

// Define variables with meaningful names
$first_name = "John";
$last_name = "Doe";

// Function to greet a person
function greet($first_name, $last_name) {
    return "Hello, " . $first_name . " " . $last_name . "!";
}

// Call the greet function
echo greet($first_name, $last_name);

?>
