What are the best practices for debugging code that involves dynamic variables in PHP?

When debugging code that involves dynamic variables in PHP, it is important to use var_dump() or print_r() functions to inspect the contents of the variables at various points in the code. This will help you identify any unexpected values or data types that may be causing issues. Additionally, using error_reporting(E_ALL) and ini_set('display_errors', 1) can help catch any warnings or notices that may be related to dynamic variables. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Debug dynamic variables
$dynamicVar = "Hello";
var_dump($dynamicVar);

// Check variable contents
if (empty($dynamicVar)) {
    echo "Variable is empty!";
} else {
    echo "Variable contains: " . $dynamicVar;
}
?>
