magento批量清除产品和分类

在magento的开发和模板调试的时候都需要加入一些分类和产品，等到网站正式上线的时候又是很麻烦的事情，所以自己写了一个php，用于清除产品和分类

<form action="" method="post">

Enter check product web:

    <input type="text" name="web"    size="40" maxlength="40"/>

    <input type="submit" name="sub" value="submit">

    </form>

<?php

$path="/var/html"        //网站的目录

//include("mysql.class.php");

if($_POST[web]){

                $web=$_POST[web];

                $xml=simplexml_load_file("/$path/$web/app/etc/local.xml");     //读取xml文件

                $dbname=$xml->global->resources->default_setup->connection->dbname;

                $password=$xml->global->resources->default_setup->connection->password;

                $username=$xml->global->resources->default_setup->connection->username;

                echo "dbname:$dbname"."<br>";

                echo "password:$password"."<br>";

$mysqli=new mysqli("localhost","$username","$password","$dbname");

//以下是清除语句
