Dear List -
Thanks for your help.
Here is another one.....
I cannot get my session variables to work. The program will print out
a chess board and show the positions of the pieces after the move
Here are code snippets: The program is chess2.php
<?php session_start();
error_reporting(1);
if (!isset($_SESSION['results'])){ //this always returns as not set.
print_r($_SESSION);
echo "starting";
$results = array(array("Br", "Bn", "Bb", "Bq", "Bk", "Bb", "Bn",
"Br"),array("Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp"),
array("", "", "", "", "", "", "",
""),array("", "", "", "", "", "", "", ""),array("", "", "", "", "",
"", "", ""),
array("", "", "", "", "", "", "",
""),array("Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp"),
array("Wr", "Wn", "Wb", "Wq", "Wk", "Wb",
"Wn", "Wr"));
$_SESSION['results'] = $results;
print_r($_SESSION);
}
else
{
$results = $_SESSION['results'];
echo "<br />starting values<br />";
print_r($results);
}
?>

for($i = 0; $i <8; $i++) // I get the correct results here
{
for ($j = 0; $j < 8;
$j++)
printf("%s ", $results[$i][$j]);
printf("<br />");
}
$_SESSION['results'] = $results;
