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：

<?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     }   }   $i=0;//reset the index,and set the mines(Random setting)   while($i < $num){//number of mine     $r = rand(0,$rows - 1);//row"s index     $c = rand(0,$cols - 1);//col"s index     if($data["data".$r."_".$c] == 0){//if not a mine       $data["data".$r."_".$c] = 100;//set the node with a mine       $i++;     }   }   for($i=0;$i<$rows;$i++){//all the rows     for($j=0;$j<$cols;$j++){//all the cols       if($data["data".$i."_".$j] == 100)continue;      //is not a mine , set number of adjacent mines        $cnt = 0;       if($i - 1 >= 0 && $j - 1 >= 0 && $data["data".($i - 1)."_".($j - 1)] == 100)$cnt++;//upper left       if($i - 1 >= 0 && $data["data".($i - 1)."_".$j] == 100)$cnt++;//left       if($i - 1 >= 0 && $j + 1 < $cols && $data["data".($i - 1)."_".($j + 1)] == 100)$cnt++;//lower left       if($j - 1 >= 0 && $data["data".$i."_".($j - 1)] == 100)$cnt++;//upper       if($j + 1 < $cols && $data["data".$i."_".($j + 1)] == 100)$cnt++;//lower       if($i + 1 < $rows && $j - 1 >= 0 && $data["data".($i + 1)."_".($j - 1)] == 100)$cnt++;//upper right       if($i + 1 < $rows && $data["data".($i + 1)."_".$j] == 100)$cnt++;//right       if($i + 1 < $rows && $j + 1 < $cols && $data["data".($i + 1)."_".($j + 1)] == 100)$cnt++;//lower right       $data["data".$i."_".$j] = $cnt;//set number     }   } }else{   $data = $_POST;//get data   if($data["data".$clickvalue] == 100){  //check the value of users click     $checkflag = 2;//if click on a mine,gameover     for($i=0;$i<$rows;$i++){//all the rows       for($j=0;$j<$cols;$j++){//all the cols         $data["open".$i."_".$j] = 1;        //set all nodes to open       }     }   }else{     $node = explode("_", $clickvalue);//get the node of click     openNode($node[0],$node[1]);//set nodes to open     for($i=0;$i<$rows;$i++){//all the rows       for($j=0;$j<$cols;$j++){//all the cols          if($data["open".$i."_".$j] == 1)$click_count++;        //get the number of opennode        }     }     if($rows*$cols - $click_count == $num)$checkflag = 1;    //if all the node is open,game clear    } } if($checkflag == 0 && $click_count == 1){//if game is start ,time start   $starttime = date("H:i:s"); } if($starttime){//Computing time and display   $now = date("H:i:s");   $nowlist = explode(":",$now);   $starttimelist = explode(":",$starttime);   $time_count = $nowlist[0]*3600+$nowlist[1]*60 + $nowlist[2] - ($starttimelist[0]*3600+$starttimelist[1]*60 + $starttimelist[2]);  $min = floor($time_count / 60);   $sec = $time_count % 60;   $timeshow = ($min>9?$min:"0".$min).":".($sec>9?$sec:"0".$sec); }else{   $timeshow = "00:00";//if game is stop , time stop } function openNode($i,$j){//set nodes to open,if it is can open   global $rows;//get the rows   global $cols;//get the cols   global $data;//get the data   if($i < 0 || $i >= $rows || $j < 0 || $j >= $cols || $data["open".$i."_".$j])return;  //it is not a node,or it has been opened   $data["open".$i."_".$j] = 1;//open the node   if($data["data".$i."_".$j] > 0)return;//need to continue?
