and one more thing....

iHorizontalMove = new int[8];

how do you create an integer array in php???

While I don't know Java so I probably wouldn't be able to help you out, I'll try to help you get started...

One thing about PHP that differs from C, Java, etc., is that it is loosely-typed. This means you don't need to declare variables or arrays, let alone specify their type. You can simply define the variable and PHP will use the appropriate type based on the value given.

In other words, this:

iCells = new int[8][8];

iCells[0][0] = 2;
iCells[0][1] = 3;
iCells[0][2] = 4;
iCells[0][3] = 4;
iCells[0][4] = 4;
iCells[0][5] = 4;
iCells[0][6] = 3;
iCells[0][7] = 2;

iCells[1][0] = 3;
iCells[1][1] = 4;
iCells[1][2] = 6;
iCells[1][3] = 6;
iCells[1][4] = 6;
iCells[1][5] = 6;
iCells[1][6] = 4;
iCells[1][7] = 3;

iCells[2][0] = 4;
iCells[2][1] = 6;
iCells[2][2] = 8;
iCells[2][3] = 8;
iCells[2][4] = 8;
iCells[2][5] = 8;
iCells[2][6] = 6;
iCells[2][7] = 4;

iCells[3][0] = 4;
iCells[3][1] = 6;
iCells[3][2] = 8;
iCells[3][3] = 8;
iCells[3][4] = 8;
iCells[3][5] = 8;
iCells[3][6] = 6;
iCells[3][7] = 4;

iCells[4][0] = 4;
iCells[4][1] = 6;
iCells[4][2] = 8;
iCells[4][3] = 8;
iCells[4][4] = 8;
iCells[4][5] = 8;
iCells[4][6] = 6;
iCells[4][7] = 4;

iCells[5][0] = 4;
iCells[5][1] = 6;
iCells[5][2] = 8;
iCells[5][3] = 8;
iCells[5][4] = 8;
iCells[5][5] = 8;
iCells[5][6] = 6;
iCells[5][7] = 4;

iCells[6][0] = 3;
iCells[6][1] = 4;
iCells[6][2] = 6;
iCells[6][3] = 6;
iCells[6][4] = 6;
iCells[6][5] = 6;
iCells[6][6] = 4;
iCells[6][7] = 3;

iCells[7][0] = 2;
iCells[7][1] = 3;
iCells[7][2] = 4;
iCells[7][3] = 4;
iCells[7][4] = 4;
iCells[7][5] = 4;
iCells[7][6] = 3;
iCells[7][7] = 2;

in PHP would simply be:

$iCells = array();

$iCells[0][0] = 2;
$iCells[0][1] = 3;
$iCells[0][2] = 4;
$iCells[0][3] = 4;
$iCells[0][4] = 4;
$iCells[0][5] = 4;
$iCells[0][6] = 3;
$iCells[0][7] = 2;

$iCells[1][0] = 3;
$iCells[1][1] = 4;
$iCells[1][2] = 6;
$iCells[1][3] = 6;
$iCells[1][4] = 6;
$iCells[1][5] = 6;
$iCells[1][6] = 4;
$iCells[1][7] = 3;

$iCells[2][0] = 4;
$iCells[2][1] = 6;
$iCells[2][2] = 8;
$iCells[2][3] = 8;
$iCells[2][4] = 8;
$iCells[2][5] = 8;
$iCells[2][6] = 6;
$iCells[2][7] = 4;

$iCells[3][0] = 4;
$iCells[3][1] = 6;
$iCells[3][2] = 8;
$iCells[3][3] = 8;
$iCells[3][4] = 8;
$iCells[3][5] = 8;
$iCells[3][6] = 6;
$iCells[3][7] = 4;

$iCells[4][0] = 4;
$iCells[4][1] = 6;
$iCells[4][2] = 8;
$iCells[4][3] = 8;
$iCells[4][4] = 8;
$iCells[4][5] = 8;
$iCells[4][6] = 6;
$iCells[4][7] = 4;

$iCells[5][0] = 4;
$iCells[5][1] = 6;
$iCells[5][2] = 8;
$iCells[5][3] = 8;
$iCells[5][4] = 8;
$iCells[5][5] = 8;
$iCells[5][6] = 6;
$iCells[5][7] = 4;

$iCells[6][0] = 3;
$iCells[6][1] = 4;
$iCells[6][2] = 6;
$iCells[6][3] = 6;
$iCells[6][4] = 6;
$iCells[6][5] = 6;
$iCells[6][6] = 4;
$iCells[6][7] = 3;

$iCells[7][0] = 2;
$iCells[7][1] = 3;
$iCells[7][2] = 4;
$iCells[7][3] = 4;
$iCells[7][4] = 4;
$iCells[7][5] = 4;
$iCells[7][6] = 3;
$iCells[7][7] = 2;

As for the "Point" class, PHP doesn't have a standard class for a point, so you can either a) create one yourself, or b) use arrays as if they were points.

For example, you could declare a point like so:

$point1 = array(1,2);

where the array would be in the format x,y. Then, to access the individual parts, you'd say:

$point1_x = $point1[0];
$point1_y = $point1[1];

You could also use an associative array, if you wanted:

$point1 = array('x' => 1, 'y' => 2);

echo $point1['x'] . ',' . $point1['y'];

As for the rest... well you can either try converting it yourself, using pseudo-code if necessary and re-posting what you come up with, or wait for someone else to come along who knows Java and is willing to do this for you (might be waiting indefinitely).

What is the KnightMoves class? Wouldn't that need to be converted to PHP as well? I don't see that you have posted the source for that...its not part of the awt package is it?

well im actually gona use it for a knight's tour algorithm
i really need it in class..... i cant find anything using web search..
if you have..

can you email me???

i appreciate your help!!!
im starting to use it now....

i think im going to wait for some more replies

Note that there is a PEAR Games_Chess package you could use. (See the getKnightSquares() method.)
