Question

我正在编写一个用于检查mgt模块的PHP代码，我需要给出试用，退出，缺陷或信誉良好的学生数量，这是在我计算出之前的cgpa，累积cgpa以及if学生们是否继续学习课程。所有这些都在for循环中，我想从for循环中得到结果。我怎么做。我的代码长度低于

我已经编辑了代码，我想要实现的目标可以被理解

foreach($aitemn as $item) {
    if ( substr($item,1,2) < 13 || (substr($item,1,2) == 13 && $mode == '2')) {

        if ($pcgpa < 1.0 && $gpa < 1.0 && $xlevel == 1) {
            $remark = 'Probation';
            $p = $p + 1;
        }
        elseif ($pcgpa < 1.0 && $gpa < 1.0 && $xlevel != 1) {
            $remark = 'Withdraw';
            $w = $w + 1;
        }
        elseif($gpa > 1.0 &&  $fc == 'NIL')  {
            $remark = 'In Good Standing'; 
            $gs = $gs + 1;
        }
        elseif ( $gpa < 1.0 && $pcgpa > 1.0) {
            $remark = 'Probation';
            $p = $p + 1;
        }      
        elseif ($fc <> 'NIL' ) {
            $remark = 'Deficient';
            $d = $d + 1;
        }
    }
    elseif (substr($item,1,2) > 12) {   

        if ($pcgpa < 1.5 && $gpa < 1.5 && $xlevel == 1) {
            $remark = 'Probation';
            $p = $p + 1;
        }
        elseif ($pcgpa < 1.5 && $gpa < 1.5 && $xlevel != 1) {
            $remark = 'Withdraw';
            $w = $w + 1;
        }
        elseif($gpa > 1.5 &&  $fc == 'NIL') {
            $remark = 'In Good Standing'; 
            $gs = $gs + 1;
        }
        elseif ( $gpa < 1.5 && $pcgpa > 1.5) {
            $remark = 'Probation';
            $p = $p + 1;
        }      
        elseif ($fc <> 'NIL' ) {
            $remark = 'Deficient';
            $d = $d + 1;
        }
    }

    $num = $num + 1;
}


<td>Number in Good Standing: <?php echo $gs;?></br>
<td>Number on Probation:     <?php echo $p;?></br>
<td>Number in Deficient      <?php echo $d;?></br>
<td>Number in Withdrawn      <?php echo $w;?></br>

好的，我想我明白你的意思。

为了让您访问foreach循环中的变量，一种方法是让您在循环中嵌套标记，如下所示：

<?php
foreach( $aitemn as $item ) {
    // your other codes
?>
<td>Number in Good Standing: <?php echo $gs;?></br>
<td>Number on Probation:     <?php echo $p;?></br>
<td>Number in Deficient      <?php echo $d;?></br>
<td>Number in Withdrawn      <?php echo $w;?></br>

<?php
} // close the foreach after the markup
?>

希望有所帮助。
