What are the implications of using cURL in a PHP function for sending data to an external API?

When using cURL in a PHP function to send data to an external API, it is important to properly handle any errors that may occur during the request. This can include checking for HTTP status codes, handling timeouts, and ensuring that the request is successful before proceeding with further processing. By implementing error handling in the cURL request, you can ensure that your application gracefully handles any issues that may arise during communication with the external API. 

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL request
$response = curl_exec($ch);

// Check for cURL errors
if(curl_errno($ch)) {
    echo 'cURL error: ' . curl_error($ch);
}

// Get HTTP status code
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);

// Close cURL session
curl_close($ch);

// Process API response
if($http_status == 200) {
    // API request was successful, process response data
    echo $response;
} else {
    // Handle API request error
    echo 'API request failed with HTTP status code: ' . $http_status;
}
