Hyperlinked Latitude and Longitude

I’m currently printing out my latitude and longitude with each post using the following code:

?php print_Lat();echo " x ";print_Lon();echo "";?>

I’m a PHP newbie. How would I get the above code to be hyperlinked to the following:

<?php print_MapQuest_Url(); ?>

So that when one clicks the latitude and longitude, the map pops open in another window?
TIA –
Matt
