This article mainly introduces the function of implementing the judge's scorer in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

1. Implementation code

<?php
function fairScore(&$arr)
{ //选择排序法的第一步，这里只需要找到这个数组中的最大值和最小值即可，没必要对整个数组排序
 $minVal = $arr[0];
 $minIndex = 0;
 $maxVal = $arr[0];
 $maxIndex = 0;
 $sum = 0;
 for ($i=1;$i<count($arr);$i++)
 {
  if ($arr[$i]<$minVal)
  {
   $minVal = $arr[$i];;
   $minIndex = $i;
  }
  if ($arr[$i]>$maxVal)
  {
   $maxVal = $arr[$i];
   $maxIndex = $i;
  }
 }
 echo "最高分是:".$maxVal." 最低分是:".$minVal."<br/>";
 for ($i=0;$i<count($arr);$i++)
 {
  $sum +=$arr[$i];
 }
 $sum -=($minVal+$maxVal);
 echo "一共有".count($arr)."个评委,去掉最高分和最低分后的平均分是".$sum/(count($arr)-2);
}
 
$score = @$_REQUEST[&#39;score&#39;];//第一次打开页面时会因为没有输入数据，所以没法提交。这里加@是为了去除浏览器notice警告
$aScore = explode(" ",$score);
 
?>
 
<html>
<head>
<title>去掉最高分和最低分后的平均分</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8"/>
</head>
 
<body>
<form action ="fairScore.php" method="post">
<span>请输入各个评委的打分，中间用空格隔开</span><br/><!--在输入时，每两个数之间只能有一个空格-->
<input type="text" name="score" value="<?php echo $score;?>" /><br/>
<input type="submit" value="提交计算平均成绩"/>
</form>
 
<?php
fairScore($aScore);
?>
</body>
<html>
