How to adding new menu in magento admin panel

Here I have Created a new Module to Add new tab in admin panel of magento.

My Namesapce Name is Anjan and My Module name is Systab

As you know to make a module first we need to make a .XML file with Namespace_Module name under app/etc/modules/ folder. So My File name will be Anjan_Systab.xml

Now I will write the following code inside this xml


<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Anjan_Systab>
            <active>true</active>
            <codePool>local</codePool>
        </Anjan_Systab>
    </modules>
</config>


As My CodePool is local which is written in Anjan_Systab.xml I will create a Folder with name Anjan inside app/code/local/, then again will create another folder with name Systab inside Anjan Folder.Now I will create an etc folder inside the Systab Folder. Inside the etc folder I will create config.xml and will write the following code


<?xml version="1.0"?>
<config>
    <modules>
        <Anjan_Systab>
            <version>0.1.0</version>
        </Anjan_Systab>
    </modules>

        <routers>
            <systab>
                <use>standard</use>
                <args>
                    <module>Anjan_Systab</module>
                    <frontName>systab</frontName>
                </args>
            </systab>
