PHP: return array? -

i have index.php, , function.php.

in index.php have included function.php

in index.php im calling login("bla","123"); exists in function.php

in index.php have if (!empty($err)){ foreach(..) echo $err ... }

login() should return array called $err, (with return $err; ) if there errors, , should echo out in foreach in index.php..

but somehow can not work. can't this? im not getting back.

i have in login() :

$err = array();     $err[] = "something went wrong";         return $err;         exit();

what's wrong here? or other solution this?

return return returns value of $err. not make variable $err globally available.

try using:

$err = login('bla', '123');
