I am not sure if this is a bug or php is just not built to handle something like this, but when i call a function like this:

function EchoContent($BarName="Error",$body="error.inc",$topheight="100",$width=$menuwidth){

it causes an error! you cant assign a variable within the function call.

i would have to re-do it like this for it not to cause an error. 

function EchoContent($BarName="Error",$body="error.inc",$topheight="100",$width="100"){

I am sure you can see the benefits of using the top version.

Variable default values are not supported.  A workaround would be to assign it a bogus value and check for that in your function.

eg.

    function foo($arg=NULL) {
        if($arg==NULL) $arg = $GLOBALS['str'];
    }
