[jQuery] .append with a var

[Nikola]

Hello, I am trying to figure out how to .append a php session $var to
a given div.  I'm not sure what the correct syntax is.  I was trying
something along the lines of how I'd display the var in HTML:

$("#someDiv").append("Some value is:<b>'.$var.'</b>");

I'm not sure the best way to go about this.  Any input is
appreciated.  Thanks much.
