How can beginners avoid errors in PHP code related to variable assignment and usage?

Beginners can avoid errors in PHP code related to variable assignment and usage by ensuring they use the correct syntax when declaring variables, paying attention to variable scope, and avoiding reusing variable names. It's important to initialize variables before using them and to properly handle data types to prevent unexpected behavior. 

// Correct way to declare and assign variables
$name = "John Doe";
$age = 25;

// Avoid reusing variable names
$first_name = "Jane";
$last_name = "Doe";

// Properly handle data types
$number = 10;
$text = "This is a string";

// Initialize variables before using them
$total = 0;
$total += $number;
