What are the best practices for debugging PHP code that involves object variables and arrays?

When debugging PHP code that involves object variables and arrays, it is essential to use var_dump() or print_r() functions to display the contents of the variables. This helps in identifying any unexpected values or structures within the objects or arrays. Additionally, using error_reporting(E_ALL) and ini_set('display_errors', 1) at the beginning of the script can help in catching any errors or notices that might occur during the execution. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Debugging object variables
var_dump($object_variable);

// Debugging arrays
print_r($array_variable);
?>
