這篇文章主要介紹了php實現的簡易掃雷游戲,涉及php字符串及流程控制的相關技巧,具有一定參考借鑒價值,需要的朋友可以參考下

本文實例講述了php實現的簡易掃雷游戲。分享給大家供大家參考。具體如下：

<?php

$init = $_POST["init"];//game restart

$clickvalue = $_POST["clickvalue"];//minesweeping

$checkflag = 0;//Victory or defeat

$click_count = 0;//clicks count

if($init == null && $clickvalue == null){//initialization

$_POST = array();//set POST with a array

$_POST["rows"] = 9;//set rows

$_POST["cols"] = 9;//set cols

$_POST["num"] = 10;//set num

$_POST["timeshow"] = "00:00"; //set starttime

$init = true;//set initialization

}

$rows = $_POST["rows"];//get rows

$cols = $_POST["cols"];//get cols

$num = $_POST["num"];//get num

$starttime = $_POST["starttime"];//get starttime

if($init){// is initialization

$timeshow = "00:00";//set starttime

$data = array();//data initialization

for($i=0;$i<$rows;$i++){//all the rows

for($j=0;$j<$cols;$j++){//all the cols

$data["data".$i."_".$j] = 0;//set mine with null

$data["open".$i."_".$j] = 0;//set node with close

}

}

while($i < $num){//number of mine

$c = rand(0,$cols - 1);//col's index

if($data["data".$r."_".$c] == 0){//if not a mine

}

}
