cURL retry in PHP

Question

Is it possible to set the option to retry on timeouts in PHP cURL?

I know I can do this by coding it to retry on failure, just wondering if there's some way to do it through an option.

you can use the errno to retry like this:

$curl = curl_init();
curl_setopt_array($curl, $options);
$response = curl_exec($curl);
$retry = 0;
while(curl_errno($curl) == 28 && $retry < 3){
    $response = curl_exec($curl);
    $retry++;
}

$error_codes=array(
    [1] => 'CURLE_UNSUPPORTED_PROTOCOL', 
    [2] => 'CURLE_FAILED_INIT', 
    [3] => 'CURLE_URL_MALFORMAT', 
    [4] => 'CURLE_URL_MALFORMAT_USER', 
    [5] => 'CURLE_COULDNT_RESOLVE_PROXY', 
    [6] => 'CURLE_COULDNT_RESOLVE_HOST', 
    [7] => 'CURLE_COULDNT_CONNECT', 
    [8] => 'CURLE_FTP_WEIRD_SERVER_REPLY',
    [9] => 'CURLE_REMOTE_ACCESS_DENIED',
    [11] => 'CURLE_FTP_WEIRD_PASS_REPLY',
    [13] => 'CURLE_FTP_WEIRD_PASV_REPLY',
    [14]=>'CURLE_FTP_WEIRD_227_FORMAT',
    [15] => 'CURLE_FTP_CANT_GET_HOST',
    [17] => 'CURLE_FTP_COULDNT_SET_TYPE',
    [18] => 'CURLE_PARTIAL_FILE',
    [19] => 'CURLE_FTP_COULDNT_RETR_FILE',
    [21] => 'CURLE_QUOTE_ERROR',
    [22] => 'CURLE_HTTP_RETURNED_ERROR',
    [23] => 'CURLE_WRITE_ERROR',
    [25] => 'CURLE_UPLOAD_FAILED',
    [26] => 'CURLE_READ_ERROR',
    [27] => 'CURLE_OUT_OF_MEMORY',
    [28] => 'CURLE_OPERATION_TIMEDOUT',
