processLegendTemplate() is for HTML templates only. You need to set 
TEMPLATE legend_template.html in your mapfile (or via mapscript), and 
then you call processLegendTemplate() which will return you a string 
buffer (HTML) of the legend that's been generated.  You can then print 
that HTML in your script output at the position where you want the 
legend to go.

With respect to $map->drawLegend(), it's for the traditional GIF legend 
and doesn't do anything with the HTML templates.
