  Sure, you can use the CoinGecko API to fetch real-time cryptocurrency prices using PHP. CoinGecko provides a simple and reliable API that allows you to retrieve the latest prices, market data, and more. You can make HTTP requests to their API endpoints using PHP's built-in functions or libraries like cURL or Guzzle. Here's a code example to get the price of Bitcoin in USD: ```php $url = 'https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd'; $response = file_get_contents($url); $data = json_decode($response, true); $bitcoinPrice = $data['bitcoin']['usd']; echo 'Bitcoin price: $' . $bitcoinPrice; ``` Remember to handle errors and exceptions properly, and also consider caching the data to avoid excessive API requests.
