How can a beginner in PHP effectively debug their code to identify and fix issues like the one described in the forum thread?

Issue: The error message "Undefined variable" is likely occurring because the variable being used in the code has not been defined before being accessed. To fix this, make sure to define the variable before using it. Code snippet: 

<?php
// Define the variable before using it
$variable = "Hello, World!";

// Access the variable
echo $variable;
?>
