[PHP] preserving variable values across pages.

[Andrew Slezak]

Found this on the php.net, querying the PHP mailing list:

">test.php
--
$blah=10;
include "whatever.php";


>whatever.php
-
echo "The value of blah is: {$blah}";


It just keeps the variable since it's global..

When ur using a function. It can be different, since you have to
import these variables."

[PHP] dynamic pulldown list generation help

[Andrew Slezak]

Basically I am setting ls > array().  I want each item to be an option in
the array.  I have have scoured for some time now and this is what I have
come up with, but it is not populating each file as an ?  The select
box is just empty.  I know this is an array because I have tested with
print_r.  Stuck!

Can someone tell me what I am doing wrong?

";
echo "";
function generate_option_list($arr1, $set) {
reset($arr1);
while (list($key,$value) = each($arr1) ) {
{$var.="$value";}
} return $var;
}

echo "";

?>

TIA,
Andy
