What are the best practices for handling API requests in PHP to ensure successful execution and response handling?

When handling API requests in PHP, it is important to follow best practices to ensure successful execution and response handling. One key practice is to properly handle errors and exceptions to prevent unexpected behavior. Additionally, using libraries like Guzzle can simplify the process of making API requests and handling responses. Finally, always sanitize and validate input data to prevent security vulnerabilities.

// Example of handling API requests using Guzzle library

// Include Guzzle library
require 'vendor/autoload.php';

use GuzzleHttp\Client;

// Initialize Guzzle client
$client = new Client();

// Make API request
try {
    $response = $client->request('GET', 'https://api.example.com/data');
    
    // Handle successful response
    $data = json_decode($response->getBody(), true);
    // Process data here
} catch (Exception $e) {
    // Handle API request error
    echo 'Error: ' . $e->getMessage();
}
