What are some recommended resources for PHP API documentation?

When working with PHP APIs, having comprehensive and well-documented resources is crucial for understanding how to interact with the API effectively. Some recommended resources for PHP API documentation include the official PHP documentation at php.net, popular PHP frameworks such as Laravel or Symfony which often have detailed API documentation, and third-party APIs like Stripe or Twilio which provide thorough documentation on how to use their services in PHP.

// Example code snippet using the Stripe PHP API documentation
require_once('vendor/autoload.php');

\Stripe\Stripe::setApiKey('sk_test_4eC39HqLyjWDarjtT1zdp7dc');

$charge = \Stripe\Charge::create([
    'amount' => 2000,
    'currency' => 'usd',
    'source' => 'tok_visa',
    'description' => 'Example charge',
]);
