How to check API request timeout by using Curl?

Question

I have a scenario. Here I'm using Curl for accessing an API. If API is not accessible, I have to send an alert email. So how can I check, if there is a request timeout?

Here is my code.

    $alerthttp1 = array();
    $string = 'somestring';
    $key = md5($string);
    $service_url = 'www.someurl.com/'.$key;

    $curl = curl_init($service_url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, 300);
    $curl_response = curl_exec($curl);
    $curl_errno = curl_errno($curl);
    $curl_error = curl_error($curl);

    error_log(json_encode($curl_errno));
    error_log(json_encode($curl_error));

    if(curl_error($curl) || $curl_response === false || $curl_errno > 0)
    {
        $info = curl_getinfo($curl);
        hlog_errorlog('error occured during curl exec - ' . var_export($info));
        hlog_errorlog('error -----------> '. $curl_error); 
        curl_close($curl);

        $alerthttp1[] = array('status' => 'FAILED');//for email alert
    }

Please suggest me, the best way of coding.

Thank you

Just check the HTTP status code of the call. php.net/manual/en/function.curl-getinfo.php — Joze

Try to use CURLOPT_CONNECTTIMEOUT instead CURLOPT_TIMEOUT CURLOPT_CONNECTTIMEOUT is the maximum amount of time in seconds that is allowed to make the connection to the server.

No you can't know it with CURL. Ask on API support. Or choose timeout time yourself. Usually it's 30 second.

CURLOPT_CONNECTTIMEOUT tells cURL the maximum amount of time to wait for the connection to complete so it will work
