Setting Curl's Timeout in PHP

Question

I'm running a curl request on an eXist database through php. The dataset is very large, and as a result, the database consistently takes a long amount of time to return an XML response. To fix that, we set up a curl request, with what is supposed to be a long timeout.

$ch = curl_init();
$headers["Content-Length"] = strlen($postString);
$headers["User-Agent"] = "Curl/1.0";

curl_setopt($ch, CURLOPT_URL, $requestUrl);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, 'admin:');
curl_setopt($ch,CURLOPT_TIMEOUT,1000);
$response = curl_exec($ch);
curl_close($ch);

However, the curl request consistently ends before the request is completed (<1000 when requested via a browser). Does anyone know if this is the proper way to set timeouts in curl?

Answer 1

See documentation: http://www.php.net/manual/en/function.curl-setopt.php

CURLOPT_CONNECTTIMEOUT - The number of seconds to wait while trying to connect. Use 0 to wait indefinitely.
CURLOPT_TIMEOUT - The maximum number of seconds to allow cURL functions to execute.

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 400); //timeout in seconds

also don't forget to enlarge time execution of php script self:

set_time_limit(0);// to infinity for example
