How can PHP developers improve their debugging process when encountering issues with array manipulation and retrieval?

When encountering issues with array manipulation and retrieval in PHP, developers can improve their debugging process by using built-in functions like var_dump() or print_r() to inspect the contents of arrays at different stages of manipulation. Additionally, using error_reporting(E_ALL) and ini_set('display_errors', 1) can help identify any errors in the code related to array manipulation. 

// Example code snippet using var_dump() for debugging array manipulation
$array = [1, 2, 3, 4];
var_dump($array);

// Example code snippet using error_reporting() and ini_set() for error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);
