Here grid is an 2d array of game's grid and ran is the next position of computer's move. 1 for [0][0], 2 for [0][1],....,8 for [2][1] and 9 for [2][2]

Default value of grid elements is ' ' and $com stands for computer's cue.

If I understand this correctly, you are checking whether 2 spots are taken up in any row, col or diagonal.

This can be simplified to checking the adjacent spot. So for corner spots such as [0][0], [0][2] etc check the adjacent spot in the row col and diagonal. For spots such as [0][1], [1][2], [1][2], and [1][0] you only need to check the centre spot because the others have been checked when you did the corners.

Adjacency can be achieved by adding or subtracting 1 from the Row or Col variables.

So the whole thing can be done with nested for loops and an adjacency function. Same thing for checking for a win.

Hope this helps.

BTW this is the first time I have seen anyone using $ as part of a variable name. It's not illegal or anything - just unusual.

I will try it. Actually it is a php's code...
