PHP code to interact with an API using the cURL library

Here's an example PHP code to interact with an API using the cURL library:

<?php

// API Endpoint URL
$apiUrl = 'https://api.example.com/endpoint';

// Request data
$data = [
    'param1' => 'value1',
    'param2' => 'value2',
];

// Create cURL resource
$curl = curl_init($apiUrl);

// Set the HTTP method and request data
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));

// Set headers
curl_setopt($curl, CURLOPT_HTTPHEADER, [
    'Content-Type: application/x-www-form-urlencoded',
    'Authorization: Bearer YourAccessToken',
]);

// Set to receive the response as a string
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

// Execute the request
$response = curl_exec($curl);

// Check for errors
if ($response === false) {
    $error = curl_error($curl);
    // Handle the error as needed
    die('cURL Error: ' . $error);
}

// Close cURL resource
curl_close($curl);

// Process the response
$responseData = json_decode($response, true);
if ($responseData) {
    // API response received successfully, do something with the data
    print_r($responseData);
} else {
    // Failed to decode the response JSON, handle the error
    die('Invalid API response');
}

?>

In this example, we assume you are making a POST request to the API endpoint https://api.example.com/endpoint and sending some data as parameters ($data). You will need to replace the $apiUrl with the actual API endpoint URL and provide the necessary request data.

After executing the request with curl_exec(), we check for any cURL errors. If there's an error, it is handled accordingly. Otherwise, the response is processed. In this example, it assumes the response is in JSON format and attempts to decode it using json_decode(). If successful, the response data is printed (print_r($responseData)). If the response couldn't be decoded, an error message is displayed.

Remember to modify the code according to the specific API you are interacting with, including the endpoint URL, request method, headers, and data format.
