Dear list -
I an writing a script that will simulate a chess board. On a move
from e2 to e6 [see below] the variable in e2 is never assigned to
e6. Here are some code snippets:
<?php
session_start();
session_name("Chess");
error_reporting(1);
if ($_SESSION['flag'] != 1)
{
$flag = 1;
echo "<br />starting<br />";
$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'] = $results;
for($i = 0; $i <8; $i++)
{
for ($j = 0; $j < 8; $j++)
printf("%s ", $results[$i][$j]);
printf("<br />");
}
$_SESSION[flag] = $flag;

$bb = $board[$value_to];

$b = $aa;
$a = '';
========
I am not able to assign the value Wp to $b which is $results[2][4].
$a, which is $results[6][4] should be empty.
Help and advice, please.
