我正在嘗試編寫一些 PHP 代碼，以便當(dāng)用戶輸入報(bào)價(jià)時(shí)，應(yīng)用程序會(huì)查看報(bào)價(jià)表，計(jì)算當(dāng)年提出的報(bào)價(jià)數(shù)量，然后將計(jì)數(shù)加 1，最終結(jié)果是提供一個(gè)那一年的唯一和連續(xù)報(bào)價(jià)編號(hào)。格式應(yīng)該是 Q/YY/sequential number//Insert New Q Reference    //set standards    $time=strtotime($values['QuoteDate']);    $LongYear=date("Y",$time);    $ShortYear=date("y",$time);    //Get current number quotes for the year which quote was issued    global $dal;    $dal_table = $dal->Table("quotations");     if ($values["QuoteDate"])        {             $rstmp = CustomQuery("select count(*) as count1 from quotations where '$LongYear' = ".$LongYear);             $datatmp = db_fetch_array($rstmp);             $count_value = 0;               if ($datatmp["count1"]) $count_value = $datatmp["count1"];            $values['QuoteReference'] = 'Q/'.$ShortYear.'/'.str_pad(($count_value+1), 4, '0', STR_PAD_LEFT);        }我遇到的問題是代碼只是返回總序列號(hào) + 1 并且沒有考慮年份的計(jì)數(shù)！看下面的截圖，2018應(yīng)該是Q/18/0001
