我將更新具有userid autoincrement屬性的coeds_user表，每當發生插入時，它會自動獲取1自動增量，然後在該字段的其餘部分插入相應的數據。到目前爲止，我已經成功插入行，但我的問題是如何更新此行時，userid是autoincrement，請你讓我知道如何實現自動增量用戶標識的更新功能，謝謝你提前。 insert_search.php如何更新數據庫行如果userID具有自動增量屬性
<?php
$user="root";
$server="localhost";
$password="";
$db="coedsproddb1";
$dbconn= mysql_connect($server,$user,$password);
mysql_select_db($db,$dbconn);
