PHP curl timeout error detection

Question

I use curl to perform a HTTP request like this:

$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);

$data = curl_exec($ch);
curl_close($ch);

How can I check if an error occurred, and whether it was a timeout error?

Curl or Divergence?

Use curl_errno()

Code 28 is timeout.

Which is named "CURLE_OPERATION_TIMEOUTED".

TIMEOUTED‽ Seriously, WTF is wrong with these people? Just to be clear, php.net's documentation (correctly) lists this unfortunate constant name. curl.haxx.se has better grammar but sadly php-curl will not recognize CURLE_OPERATION_TIMEDOUT.

Mark Amery Over a year ago

@Lambart apparently CURLE_OPERATION_TIMEOUTED was the original constant name used by curl, which they then changed to CURLE_OPERATION_TIMEDOUT while keeping the former as a now-undocumented alias. The latest version of PHP supports both; see the comment at php.net/manual/en/curl.constants.php#117928 for some history.

@MarkAmery glad they finally got that fixed up.

you can check error number and its' description like this:

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

if you use curl as an Object, it would be much nicer.
