Are there any potential pitfalls or common mistakes to watch out for when using cURL in PHP?

One potential pitfall when using cURL in PHP is not properly handling errors or checking for successful responses. It's important to check for errors, HTTP status codes, and handle any exceptions that may occur during the cURL request. This can prevent unexpected behavior or issues with your application. 

// 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);
} else {
    $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    
    if($http_status != 200){
        echo 'HTTP error: ' . $http_status;
    } else {
        // Process successful response
        echo $response;
    }
}

// Close cURL session
curl_close($ch);
