What are best practices for troubleshooting PHP scripts that interact with external systems or APIs, such as Owncloud?

When troubleshooting PHP scripts that interact with external systems or APIs like Owncloud, it's important to check for errors in the code, ensure proper authentication credentials are being used, and verify that the API endpoints are accessible. Additionally, logging errors and responses can help identify issues and debug effectively. 

// Example PHP code snippet for troubleshooting Owncloud API interaction

// Set up cURL session
$ch = curl_init();
$url = 'https://owncloud.example.com/endpoint';
$headers = array(
    'Authorization: Bearer YOUR_ACCESS_TOKEN',
    'Content-Type: application/json'
);

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

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

// Check for errors
if($response === false){
    echo 'cURL error: ' . curl_error($ch);
} else {
    // Log response
    file_put_contents('response.log', $response);
}

// Close cURL session
curl_close($ch);
