problem with user's login name


i've a trouble with a php script:


$uname[1] = "test";
$upass[1] = "test";
$known_as[1] = "test user";


// check through all the users to see if they exist
for ($i = 1; $i <= $user_count; $i++) {
if ($uname[$i] == $username && $upass[$i] == $password){
$welcome = $known_as[$i];
$user_exists = true;


Now is the main problem: if i call the $welcome var in the logged
page, it won't print the user name... why?

I use:


and doesn't work...

Probably your variables are out of scope
function foo() {
// notice (undefined variable: a) on next line
echo $a; // local $a (to the foo() function)

function bar($a) {
echo $a; // local $a -- different than the global $a

function taz() {
global $a;
echo $a; // NOW the same $a as previously defined

$a = 'global';
$b = 'also global';

echo $a; // use the global and print "global"
foo(); // prints nothing (except perhaps the notice)
bar($a); // prints "global", but it's just a coincidence
bar($b); // prints "also global"
taz(); // prints "global"
