Utilisez mysql REPLACE INTO ou INSERT... ON DUPLICATE KEY UPDATE . Par exemple :
foreach ($sheet as $data) {
// Get Phone ID
$dataPhoneID = mysql_escape_string($data['handset']['phone_id']);
if (isset($stocks[$dataPhoneID])) {
$stockPhone = $stocks[$dataPhoneID ];
$phoneName = mysql_escape_string($stockPhone['description']);
$stock = mysql_escape_string($stockPhone['stock']);
$SQLInsert = "INSERT INTO phone_affiliate (affiliate_id, affiliate_phone_id, stock) ";
$SQLInsert .= "VALUES ('1', '$dataPhoneID', '$stock') ";
$SQLInsert .= "ON DUPLICATE KEY UPDATE stock = '$stock'";
mysql_query($SQLInsert);
if (mysql_insert_id()) {
$SQLInsert = "INSERT INTO phone (name) VALUE('$phoneName')";
mysql_query($SQLInsert);
$phone_id = mysql_insert_id();
$SQLUpdate = "UPDATE phone_affiliate set phone_id = $phone_id WHERE affiliate_id = 1 AND affiliate_phone_id = $dataPhoneID_id";
}
}
}
