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

PHP beginners can avoid errors related to variable declaration and usage by ensuring that variables are declared before they are used, using meaningful variable names, and paying attention to data types. To prevent errors, beginners should also initialize variables before using them to avoid undefined variable errors. 

<?php

// Declare and initialize variables
$name = "John";
$age = 25;

// Use the variables in the code
echo "My name is " . $name . " and I am " . $age . " years old.";

?>
