What are some common pitfalls when working with API response arrays in PHP?

One common pitfall when working with API response arrays in PHP is assuming that the array keys will always exist. To avoid errors, it's important to check if a key exists before trying to access its value. Another pitfall is not handling nested arrays properly, which can lead to unexpected results. It's best to use functions like isset() or array_key_exists() to safely access array values. 

// Check if a key exists before accessing its value
if (isset($apiResponse['key'])) {
    $value = $apiResponse['key'];
    // Do something with $value
}

// Handle nested arrays safely
if (isset($apiResponse['nested']['key'])) {
    $nestedValue = $apiResponse['nested']['key'];
    // Do something with $nestedValue
}
