[SOLVED] Are string variables passed by ref or value

I believe it will be the value of that not the refs as you can put direct text input, it will take those comma separated values and apply those as new memory refs for the function's life.

<?php
$var = "Foo";
function stuff($vardata){
return $vardata;
}
$var2 = stuff($var);
$var3 = stuff("Foo");
var_dump($var2);
var_dump($var3);
?>

I Know what you are talking about because I too have seen it in C the pointers to a mem reference and not the string value, I haven't seen a useful place for it in php, but maybe bridging the gab between php and another language such as C might have its usefulness.  Of course the question then becomes how do you find it as it will be random usually
