Minesweeper PHP class
What is minesweeper?
The goal of the game is to find where are all the mines within a game field. There are no rules that limit the size of mine field, however there are some typical sizes, like 10x10 fields, with 10 mines hidden, 16x16 with 40 mines hidden and so on. To help you, the game shows a number in a square which tells you how many mines there are adjacent to that square. For instance, supose the following 4x4 field with 2 mines (which are represented by an * character):
*...
....
.*..
....
If we would represent the same field placing the hint numbers described above, we would end up with:
*100
2210
1*10
1110
As you may have already noticed, each square may have at most 8 adjacent squares.
What this class offers?
This class offers you a really simple way for creating your own Minesweeper games with a game field size of your choice.
How does it work?
I've created a sample minesweeper game for you:
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
session_start();
?>

}
// print the game field
echo $ms -> BuildXHTML();
// save game field variables into session for later use. You can also

$_SESSION['minesweep'] = $ms -> DumpVars();
// Let's print number of fields left
if ($ms -> FieldsOpen - $ms -> MineCount != 0){
echo '<p>'. ($ms -> FieldsOpen - $ms -> MineCount) . ' fields left</p>';
}else{
echo '<p>No fields left!</p>';
}
