I have a list of cities.

<select name="cities">
    <option value="nc">New city..</option>
    <option value="quetta">Quetta</option>
    <option value="karachi">Karachi</option>
    <option value="islamabad">Islamabad</option>
    <option value="khyber pukhtun khuan">Khyber Pukhtun Khuan</option>
    <option value="multan">Multan</option>
    <option value="murree">Murree</option>
    <option value="gwadar">Gwadar</option>
    <option value="gujranwala">Gujranwala</option>
    <option value="faisalabad">Faisalabad</option>
    <option value="peshawar">Peshawar</option>
</select>

And i have a database in which i have stored user's city. Now i am making a page in which the user will update his city and for that i want the user to see his city already selected when he opens up the page. In short, i want a option to be selected according to the value returned by the database. I am using php as the language

I have got one solution but not implemented it yet because its not effecient! Any easy and effecient way would be appreciated.

Thanks in advance :)
