// Issue: Undefined index error when accessing an array element that does not exist
// Solution: Check if the array key exists before accessing it to avoid the error

if (array_key_exists('key', $array)) {
    $value = $array['key'];
    // continue with processing the value
} else {
    // handle the case when the key does not exist
}
