Hi Jacques, thanks for this. This is just speculation. Because I think that the cUrl doesn't retry automatically but the TCP protocol does : if TCP not getting its ACK so it re-sends the packet a couple of times, does not it? And this situation is very rare/exceptionnel 1%! When the "total_time" (by [curl_getinfo]) is more than 7 second.

can you some idea for me ?

Hi Jacques1, many thanks When you say "your service", is it web service which I use, isn't it ? So this web service provided us by our supplier. So I can not any control this web service : I must ask to change to our provider ? Or I must add something in my script ? What is a nonce ? It means a token ? Where can I put this token ? I can create a unique/single token with "microtime" + order number, is it right ? Before "curl_close" line 84? Here is my code : include 'includes/info.php'; include 'includes/functions.php'; $micro_date = microtime(); $date_array = explode(" ",$micro_date); $nowDate = date("Y_m_d__H_i_s__",$date_array[1]); define('KEY_SECRET', $key_shared_secret); function verify_webHk($dataIn, $hmac_header) { $calculated_hmac = base64_encode(hash_hmac('sha256', $dataIn, KEY_SECRET, true)); return ($hmac_header == $calculated_hmac); } $hmac_header = $_SERVER['HTTP_X_HMAC_SHA256']; $dataIn; $dataIn = file_get_contents('php://input'); $verified = verify_webHk($dataIn, $hmac_header); $dataInDecode = json_decode($dataIn); $dataInDecodeArray = json_decode($dataIn, true); $nowDateFile = date("Ymd"); $orderNumber = $dataInDecodeArray['orderNumberJsn']; $logFileName = '\sent_response_' . $orderNumber . '_' . $nowDateFile. '.txt'; $logFileNameConnexion = '\error_connexion_' . $orderNumber . '_' . $nowDateFile. '.txt'; $orderNumber = $dataInDecode->orderNumberJsn; foreach ($dataInDecode->lineItems as $objProd) { switch($objProd->trader) { case 'TraderPeekABoo' : $errorNumberCurl = NULL; $errorTitleCurl = NULL; $searchID = funcFind(array("*-","--","=="),$objProd->nsm); $productID = $searchID[0]; $priceItems = $objProd->priceItems; $pricesTaxs = (array)$objProd->taxLines; $tax1st = !empty($pricesTaxs[0]) ? $pricesTaxs[0]->priceItems : 0.00; $tax2nd = !empty($pricesTaxs[1]) ? $pricesTaxs[1]->priceItems : 0.00; $total = $priceItems + $tax1st + $tax2nd ; $commandXML = '<?xml version="1.0" encoding="utf-8"?> <command> <traderId>' . $orderNumber . '</traderId>'; $commandXML .= '<commandItem> <faceValue>' . number_format($total, 2, '.', '')*100 . '</faceValue> '; $commandXML .= '</commandItem></command>'; $urlWS = $url . $productID. '?account=' . $account . '&key=' . $key ; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $urlWS); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query(array('xml' => $commandXML))); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); $dataOut = curl_exec($curl); $infoOut = curl_getinfo($curl); $logData = "\r\n" .'Information transfer :'. "\r\n" . serialize($infoOut) . "\r\n" .'result :'."\n". $dataOut. "\r\n"; if(curl_errno($curl)) { $errorNumberCurl = curl_errno($curl); $errorTitleCurl = curl_error($curl); } curl_close($curl); if($errorNumberCurl) { $dataLogError = "\r\n" .'CURL\'S Error number: "' . $errorNumberCurl . '" and Error info: "'. $errorTitleCurl. '"'."\r\n"; file_put_contents($logDirectory.$logFileNameConnexion, $dataLogError, FILE_APPEND | LOCK_EX); } file_put_contents($logDirectory.$logFileName, $logData, FILE_APPEND | LOCK_EX); break; default: // echo '<p>NOTHING</p>'; break; } } exit();

Hi, I have a PHP script using the cURL function. This script send the data by a web service. It works often without problem. Sometimes, he sent a double data : same data by two times. I checked the log file this script (by curl_getinfo) on "total_time" When this script works correctly (it send the data only one time) : the total_time is less than 6 second. but when the total_time is more than 7 second, (this is a casual/occasional situation), my script send same data by two times so it is double data! So the web service send the ACK(Acknowledgment) which takes a long time (more than 7 second) and then, the TCP send again same data to a web service. How can I avoid this doubling ? By increasing this time waiting / time limit ? How can I define this time limit for 12 second? Could you help me : Thanks
