如何使用php

将此查询字符串中的表名替换为另一个字符串或表名

SELECT 
    Panel.Id as PanelId,Panel.Title as PanelTitle,Panel.Icon as PanelIcon,
    SubPanel.Id as SubPanelId,SubPanel.Title as SubPanelTitle,
    SubPanel.Icon as SubPanelIcon,SecurityAccess.Id as Access,SecurityAccess.Controller,
    SecurityAccess.Action
FROM Panel
INNER JOIN SubPanel
INNER JOIN SecurityAccess
WHERE 
Panel.Id > 0 AND SubPanel.Panel = Panel.Id AND SubPanel.Id = UsersAccess.Subpanel
and SubPanel.Id > 0
ORDER BY Panel._Order,SubPanel._Order

例如：替换＆＃34; Panel＆＃34;与＆＃34; my_panel＆＃34;

我不想让你改变我的字符串。只需使用此字符串即可。

我希望这可以帮助你......

$sql = "SELECT 
            $table_1.Id as PanelId, $table_1.Title as PanelTitle, $table_1.Icon as PanelIcon,
            $table_2.Id as SubPanelId, $table_2.Title as SubPanelTitle,
            $table_2.Icon as SubPanelIcon, $table_3.Id as Access, $table_3.Controller,
            $table_3.Action
        FROM $table_1
        INNER JOIN $table_2
        INNER JOIN $table_3
        WHERE 
        $table_1.Id > 0 AND $table_2.Panel = $table_1.Id AND $table_2.Id = UsersAccess.Subpanel
        and $table_2.Id > 0
        ORDER BY $table_1._Order, $table_2._Order";

您当前的查询它会像..

$table_1 = "Panel";
$table_2 = "SubPanel";
$table_3 = "SecurityAccess";

如果$ table_ vars是用户输入，则在进行查询之前要小心逃避它们。
