What are some best practices for handling cURL requests in PHP to ensure successful results?

When handling cURL requests in PHP, it is important to set appropriate options to ensure successful results. Some best practices include setting the CURLOPT_RETURNTRANSFER option to true to return the response as a string, handling potential errors using curl_error() and curl_errno(), and closing the cURL session after the request is complete. 

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

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

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

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

// Close cURL session
curl_close($ch);

// Process the response
echo $response;
