php实现的简易扫雷游戏实例

本文实例讲述了php实现的简易扫雷游戏。分享给大家供大家参考。具体如下：

2. $init = $_POST["init"];//game restart
3. $clickvalue = $_POST["clickvalue"];//minesweeping
4. $checkflag = 0;//Victory or defeat
5. $click_count = 0;//clicks count
6. if($init == null && $clickvalue == null){//initialization
7. $_POST = array();//set POST with a array
8. $_POST["rows"] = 9;//set rows
9. $_POST["cols"] = 9;//set cols
10. $_POST["num"] = 10;//set num
11. $_POST["timeshow"] = "00:00"; //set starttime
12. $init = true;//set initialization
13. }
14. $rows = $_POST["rows"];//get rows
15. $cols = $_POST["cols"];//get cols
16. $num = $_POST["num"];//get num
