Schaakbord tekenen
Dus chessBoard(6,4) function returns deze array:
[
["O","X","O","X"],
["X","O","X","O"],
["O","X","O","X"],
["X","O","X","O"],
["O","X","O","X"],
["X","O","X","O"]
]
En chessBoard(3,7) returns dit:
[
["O","X","O","X","O","X","O"],
["X","O","X","O","X","O","X"],
["O","X","O","X","O","X","O"]
]

... die meerdere arrays genereert na de comma?
D'r is wel zo iets als een for-loop. Dat 2x (hoogte/breedte) en je hebt je schaakbord.

Een schaakbord is 8 op 8 en kan best als een dubbele array weergegeven worden.
Mijn bord is bijvoorbeeld:
Code (php)
1
2
3
4
5
6
7
8
9
10
11
12
2
3
4
5
6
7
8
9
10
11
12
$bord = array( array("1", "2", "2", "2", "2", "2", "2", "2", "2", "3", " "),
array("4", "R", "N", "B", "Q", "K", "B", "N", "R", "5", " "),
array("4", "P", "P", "P", "P", "P", "P", "P", "P", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", "p", "p", "p", "p", "p", "p", "p", "p", "5", " "),
array("4", "r", "n", "b", "q", "k", "b", "n", "r", "5", " "),
array("6", "7", "7", "7", "7", "7", "7", "7", "7", "8", " "),
array(" ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ")
);
array("4", "R", "N", "B", "Q", "K", "B", "N", "R", "5", " "),
array("4", "P", "P", "P", "P", "P", "P", "P", "P", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", " ", " ", " ", " ", " ", " ", " ", " ", "5", " "),
array("4", "p", "p", "p", "p", "p", "p", "p", "p", "5", " "),
array("4", "r", "n", "b", "q", "k", "b", "n", "r", "5", " "),
array("6", "7", "7", "7", "7", "7", "7", "7", "7", "8", " "),
array(" ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ")
);
Waarbij 0 en 9-10 borders zijn.
Mijn kleur, zwart links onder, wordt berekend met een xor
Hoewel ook werkende van SanThe: $boolean = !$boolean; is de variable overbodig met een xor
