这里我要删除数据库记录，当我删除记录时，记录删除成功但是它重新加载insert_search页面显示结果并且删除的结果不会去，所以我需要输入每次在url中使用insert_search获取更新结果时，请告诉我需要重新加载页面以及如何实现它，请提前感谢...
<?php
$user = "root";
$server = "localhost";
$password = "";
$db = "coedsproddb1";
$dbconn = mysql_connect($server, $user, $password);
mysql_select_db($db, $dbconn);
?>

答案 0 :(得分：0)
使用
echo "<script>location.replace('user_delete.php');</script>";
而不是标头位置。 希望这会有所帮助。
