How can debugging be improved when working with arrays in PHP to avoid notices and errors?

When working with arrays in PHP, it's important to check if the array key exists before accessing it to avoid notices and errors. This can be done using functions like isset() or array_key_exists(). Additionally, enabling error reporting and displaying errors can help in identifying and fixing issues related to arrays. 

// Example of checking if array key exists before accessing it
$array = ['key' => 'value'];

if (isset($array['key'])) {
    echo $array['key'];
} else {
    echo "Key does not exist";
}
