What are the common pitfalls to avoid when using cURL in PHP scripts?

One common pitfall to avoid when using cURL in PHP scripts is not handling errors properly. It is important to check for cURL errors and handle them gracefully to prevent unexpected behavior in your application. Another pitfall is not setting the appropriate cURL options, such as setting the user agent or timeout values, which can lead to inefficient or unreliable requests. Additionally, not securely handling sensitive data, such as API keys or passwords, when making cURL requests can pose a security risk. 

// Example code snippet demonstrating proper error handling and setting cURL options

$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'MyApp/1.0');
curl_setopt($ch, CURLOPT_TIMEOUT, 10);

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

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

// Close cURL resource
curl_close($ch);

// Process the response data
if($response){
    // Handle the response data here
    echo $response;
} else {
    echo 'No response received';
}
