How can error reporting be used effectively in PHP to identify and resolve issues like accessing array offsets on null values?

When accessing array offsets on null values in PHP, it can lead to errors like "Trying to access array offset on value of type null". To effectively identify and resolve this issue, you can use error reporting to catch and handle these errors. By checking if the array key exists before accessing it, you can prevent errors related to null values. 

// Enable error reporting to catch issues like accessing array offsets on null values
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example code to access array offset safely by checking if the key exists
$array = ['key' => 'value'];
$key = 'non_existent_key';

if (array_key_exists($key, $array)) {
    echo $array[$key];
} else {
    echo "Key does not exist in the array.";
}
