Question

<?php
$startX = 2;
$startY = 5;

$fieldHeight = 6;
$fieldWidth = 6;

$player[2][5] = 1;


echo "<table>";
for ($y=$startY; $y<$fieldHeight+$startY+$fieldHeight; $y++) {
   echo "<tr>";
   for ($x=$startX; $x<$fieldWidth+$startX+$fieldWidth; $x++) {
       echo "<td>";
        if (isset($player[$x][$y])) {
            echo "UID: " . $player[$x][$y];
        } else {
            echo "(" . $x . ", " . $y . ")";
        }
       echo "</td>";
   }
   echo "</tr>";
}
echo "</table>";

Would output:

UID: 1  (3, 5)  (4, 5)  (5, 5)  (6, 5)  (7, 5)  (8, 5)  (9, 5)  (10, 5) (11, 5) (12, 5) (13, 5)

As you can see in the left TOP corner, the UID: 1 is placed, I want it in the middle, but I don’t know how…

I guess I would need do take the coordinates, below the startX or something, but what if there is – coordinates, I would just put out a specific test instead, is this possible?

Answer 1

Ok so

$startX = 2;
$startY = 5;

$player[2][5] = 1;

You then ask for two for loops using $startX and $startY as the base integers for the loop. Therefore the first item to be printed out will be $player[2][5] (or $player[$startX][$startY]) based on your if clause.

To demo where you’ve gone wrong with your current script: Change $startX = 1; and $startY = 1 and the UID will be printed at $x = 2 and $y = 5.
