FAQs

Questions about using our API with PHP? Below are some of our most asked questions or feel free to get in touch.

How do I install the PHP SDK?

Install our PHP SDK using Composer: composer require houseofapis/currencyapi. The SDK is available on Packagist and supports PHP 7.2 and higher.

Once installed, use it with: use HouseOfApis\CurrencyApi\CurrencyApi;. Then create an instance with your API key to start making requests.

Do I need to use the SDK, or can I use HTTP clients directly?

You can use either approach! The SDK provides a cleaner, more object-oriented interface with built-in error handling and fluent methods.

If you prefer, you can use Guzzle, cURL, file_get_contents(), or any HTTP client library directly with our REST API. Both approaches are fully supported and documented.

Does the PHP SDK support namespaces and PSR standards?

Yes, the PHP SDK follows PSR-4 autoloading standards and uses proper namespaces.

If you want to find out more, checkout out the code in the PHP SDK GitHub repository.

Can I use this with Laravel, Symfony, or WordPress?

Absolutely! Our PHP Currency API works seamlessly with Laravel, Symfony, WordPress, CodeIgniter, and any PHP framework or CMS.

You can integrate it into controllers, create service providers, or use it in plugins. Check our PHP SDK Documentation for framework-specific examples.

What PHP versions are supported?

Our PHP SDK supports PHP 7.2 and higher. For direct API calls using HTTP clients like Guzzle or standard PHP functions, any PHP version that supports these will work.

We recommend PHP 7.4+ for the best experience and latest language features like typed properties and arrow functions.

How do I handle errors in PHP?

Use PHP's try/catch blocks. The SDK throws exceptions for API errors, network issues, and invalid requests.

Wrap your API calls: try { $result = $currencyApi->rates(); } catch (\Exception $e) { echo $e->getMessage(); }. See our Error Handling Documentation for detailed examples.
