functions that declare variables

[Anon]

It it possible to run a function that simply declares a group of variables based on the supplied argument?

for exaple:

<?
function test ($var) {
$uppercase = strtoupper ($var);
$uppercase_first = ucfirst ($var);
$reverse = strrev ($var);
}
test ('hello');
?>

now I could do
echo "$uppercase, $uppercase, $reverse";
and get: HELLO, Hello, olleh

I realize the above code does not work but what is the best way to achieve this idea?

try....

<?
function test ($var) {
$test_array['upper'] = strtoupper ($var);
$test_array['ucfirst'] = ucfirst ($var);
$test_array['reverse'] = strrev ($var);

return $test_array;
}

$array = test ('hello');

while (list ($key, $val) = each ($array)) {
print "$key = $val <BR>";
}

?>

this should print the following...

upper = HELLO
ucfirst = Hello
revers = olleh

Macks,

Thank you for the response. I guess a function can only return a single variable?That's why the one variable must be an array to store multiplte variables.
