Updating innerHTML with HTML from a php function? (using xajax) -

i'm updating innerhtml of div through xajax (when click link) when assign html in function itself, not when call different function.

to explain

  // sake of testing $output=rand(20,40);    // add new html container through $output $ajax_resp->assign('div_container','innerhtml', $output);  return $ajax_resp; 

this works fine. when call function through clicking link, container updates random number. when change $output to

$output=$compile->show('text'); 

which (simplified)

function show($var) { echo $var; }

it not show it. function show works outside of xajax. suggestions?

function show($var) { echo $var; } 

this function doesn't return anything, echo's value screen. however, functions want return value, can work it. basically, when do

$output=$compile->show('text'); 

it no input show method, because show doesn't return value. think if change following:

function show($var) { return $var; } 

it work.
