如何停止子课程的foreach循环？

Question

当我点击Linuxbasics时，如果默认页面在那里，它应该打开。我正在获取默认页面，但我的li正在循环。在我的代码中，我使用了多维数组。下面是我的代码和图像。我在Image中显示我得到两次linux基础知识：

<ul class="sub-menu" style="border-right: 2px solid #012340;">
<?php foreach($outContentArrResults AS $keyCmsId => $valArrMenu){?>
    <?php if($valArrMenu['cPId']==0){?>
        <li class="menu-item-has-children">
            <a href="#"><?php echo isset($valArrMenu['cName']) ? $valArrMenu['cName']:'';?></a>
            <?php $slugName = isset($valArrMenu['cSName']) ? $valArrMenu['cSName']:'';
            $id =isset($valArrMenu['cId']) ? $valArrMenu['cId']:'';
            $courseChild =isset($valArrMenu['courseChild']) ? $valArrMenu['courseChild']:'';?>
        <?php foreach($courseChild AS $keyId => $courseResult){
        if($courseResult['cPId']==$id){?>
            <ul class="sub-menu" style="border-right: 2px solid #012340;border-left: 2px solid #012340;">
                <?php foreach($courseChild AS $keyId => $courseResult){?>
                <?php if($courseResult['cPId']==$id){?>
                <?php $courseSubChild =isset($courseResult['courseChild']) ? $courseResult['courseChild']:'';
                    foreach($courseSubChild AS $keyIdsss => $courseSubResult){
                    $Subid =isset($courseSubResult['cId']) ? $courseSubResult['cId']:'';
                    $SubslugName =isset($courseSubResult['cSName']) ? $courseSubResult['cSName']:'';?>
                        <li>
                            <a href="<?php echo $config['LIVE_URL'];?>courses/<?php echo isset($slugName) ? $slugName :'';?>/<?php echo isset($courseResult['cSName']) ? $courseResult['cSName']:'';?>/<?php echo $SubslugName;?>/<?php echo isset($courseSubResult['conSName']) ? $courseSubResult['conSName']:'';?>"><?php echo isset($courseResult['cName']) ? $courseResult['cName']:'';?></a>
                        </li>
                    <?php }?>
                <?php }?>
                <?php }?>
            </ul>
        <?php }?>
        <?php }?>
        </li>
    <?php }?>
<?php }?>

这是我的阵列：

Answer 1

您可以将数值存储在数组casue中，而不是它的初始状态 foreach循环导致问题

然后使用if（！in_array（））仅打印不存在的值

Answer 2

As＆＃34; BeetleJuice＆＃34;提到，尝试首先使用纯PHP代码测试逻辑，然后与HTML集成，这将简化工作。

关于你的代码，你的内心循环似乎有错误的数据打印。只需在代码中进行以下更改即可确定问题：而不是

<li>
                    <a href="<?php echo $config['LIVE_URL'];?>courses/<?php echo isset($slugName) ? $slugName :'';?>/<?php echo isset($courseResult['cSName']) ? $courseResult['cSName']:'';?>/<?php echo $SubslugName;?>/<?php echo isset($courseSubResult['conSName']) ? $courseSubResult['conSName']:'';?>"><?php echo isset($courseResult['cName']) ? $courseResult['cName']:'';?></a>
                </li>

                run this,

                <li>
                    <?php echo $courseResult['cId']?>
                </li>

由于每个级别的记录都有唯一的cid，因此您可以轻松找到问题。

希望这有帮助。
