variable in function parameter

[386-Dx]

Hello. Let's say I have something like this:

function aa($test) {
$a = 8;
echo $test;
}

$a = 2;
aa("a is ". ($a>5?"greater":"equal to or less"). " than 5".);


I want this to output "a is greater than 5".. how can i modify the code so
that the function parameter is evaluated inside the function?

No... you need to make $a global within the function for that change to
affect $a outside the function

function (...)
{
global $a;
$a = 8;

(can maybe do that in one operation, try it and see)

A yes, I did forget to mention that but as per requested I was
assuming they wanted the string test to be evalulated.

<snip>
I want this to output "a is greater than 5".. how can i modify the
code so that the function parameter is evaluated inside the
function?

Yes.

I simplified the example for clearance but what I really want is to send a
string as a parameter which includes variable names to be processed inside
the function. eval() works fine, but I'm sure there was another way.
