use a var inside a function

hay. fastest way to explain will be just give example.

$vid = 5

function test() {
$my_vid_inside_function = $vid
}

i want that $my_vid_inside_function will be equal to 5.
in other words, how i use an outside var inside a function?

<?php

$vid = 5;
test_ref($vid); // pass in $vid as a reference
test_glob(); // access $vid as a global

function test_ref(&$vid) {
$my_vid_inside_function = $vid;
echo "Ref: $my_vid_inside_function\n";
}

function test_glob() {
global $vid;
$my_vid_inside_function = $vid;
echo "Global: $my_vid_inside_function\n";
}

/* Result:
Ref: 5
Global: 5
*/

?>
