Executing a PHP function in a variable?

[FuzzyLogik]

I have a function,

function output($output) {
echo $output;
}

I have a variable,
$myvar = 'This is my variable. The output is X';

How do I combine the two?

I've tried:

$myvar = 'This is my variable. The output is' . output("this thing");

But no such luck.

Heh, my fault actually.

I guess I should be using "return" instead of "echo" for functions :)

Doesn't work for you? That works for me just fine. Does your file have a .php extension or is htaccess to prase the html properly?

Echo and Return are extremely different concepts that in certain circumstances can acheive the same result. Read up on the output buffer.
