How do I handle errors in curl?

You can handle errors in curl by checking the return code using curl_errno() and curl_error() functions.

Can you give me an example of how to implement that?

Sure! Here's a simple example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com');
$response = curl_exec($ch);

if(curl_errno($ch)) {
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);

What are some common curl error codes I should know about?

Common curl error codes include:

• CURLE_COULDNT_CONNECT (7): Failed to connect to the server.
• CURLE_HTTP_RETURNED_ERROR (22): HTTP response code indicates an error.
• CURLE_OPERATION_TIMEOUTED (28): Operation timeout.

Is there a way to log these errors for later review?

Yes, you can log errors by writing them to a file or a logging system. For example:

if(curl_errno($ch)) {
    file_put_contents('curl_errors.log', curl_error($ch) . "\n", FILE_APPEND);
}
