Hi Bobby
The following is a copy and paste of the page I'm using to
generate the problem. I have 18 keys in the $_SESSION
variable and just by simply refreshing the page with the
following code, it returns either array(0){} or session info and
array(18){ will all the correct variables }. I must be doing
something fundamentally wrong somewhere.
Thanks very much for your willingness to help me.
<?php
session_start();
?>
<html>
<head>
</head>
<body>
<?php
foreach( $_SESSION as $key => $value )
{
echo "<font color=\"FF9900\">SESSION[$key] = $value<br>";
}
echo "<br><br>";
var_dump( $_SESSION );
?>
</body>
</html>
