Embed Google Map code in HTML with marker

Question

I have several places with their latitude and longitude. I want to display them in google map. Thats ok, what i can't is to display the marker at the specific lat,long position.

e.g. if i've the following code, is it possible just to place an option to display the market as well because all the lat,long coord are comming from a database and echoed with php

<iframe width="425" height="350" frameborder="0" scrolling="no" 
        marginheight="0" marginwidth="0" 
        src="http://maps.google.mu/?ie=UTF8&amp;ll=-20.234496,57.603722&amp;spn=0.093419,0.169086&amp;t=m&amp;z=13&amp;
        output=embed"></iframe>
        <br />
        <small><a href="http://maps.google.mu/?ie=UTF8&amp;ll=-20.234496,57.603722
                  &amp;spn=0.093419,0.169086&amp;t=m&amp;z=13&amp;source=embed"
               style="color:#0000FF;text-align:left">View Larger Map
               </a>
        </small>
