How can developers ensure better error reporting and debugging in PHP scripts to avoid issues like undefined variables?

To ensure better error reporting and debugging in PHP scripts to avoid issues like undefined variables, developers can enable error reporting, use isset() or empty() functions to check variable existence, and utilize debugging tools like Xdebug. 

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

// Check if variable is set before using it
if(isset($variable)){
    // Use the variable here
} else {
    // Handle the case where the variable is undefined
}
?>
