How can errors and debugging be improved in PHP scripts to identify issues like incorrect variable indexing?

To improve error identification in PHP scripts, it is essential to enable error reporting and display error messages. Additionally, using debugging tools like Xdebug can help trace and identify issues such as incorrect variable indexing. By thoroughly testing the code and utilizing tools like var_dump() or print_r() to inspect variables, developers can quickly pinpoint and resolve problems related to variable indexing. 

// Enable error reporting and display error messages
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Use var_dump() to inspect variables for incorrect indexing
$myArray = array('apple', 'banana', 'cherry');
var_dump($myArray[3]); // This will output an error for incorrect indexing
