What are some common pitfalls to be aware of when using Curl to send data via PHP?

One common pitfall when using Curl to send data via PHP is not properly handling errors. It is important to check for Curl errors and handle them appropriately to prevent unexpected behavior in your application. Another pitfall is not setting the appropriate Curl options, such as the request method or headers, which can result in incorrect data being sent or received. Additionally, not properly sanitizing user input before sending it with Curl can lead to security vulnerabilities. 

// Initialize Curl
$ch = curl_init();

// Set Curl options
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/data');
curl_setopt($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($ch)){
    // Handle Curl error
    echo 'Curl error: ' . curl_error($ch);
}

// Close Curl
curl_close($ch);
