PHP 使用递归方式将其二维数组整合为层级树其中层级id 为一个uuid的格式造成的诡异问题已解决

不啰嗦直接上源代码

<?php
function findChildren($list, $p_id){
        $r = array();
        foreach ($list as $k => $item) {
            if ($item['fid'] == $p_id) {
                unset($list[$k]);
                $length = count($r);
                $r[$length] = $item;
                if ($t = findChildren($list, $item['id'])) {
                    $r[$length]['children'] = $t;
                }
            }
        }
        return $r;
}

function findChildren2($list,$p_id,&$sike=[]) {
    $r = array();
    foreach($list as $k=>$item) {
         if($item['fid']==$p_id && !in_array($item['id'],$sike)) {
	    $menu = $item;
            array_push($sike,$item['id']);
	    $children = findChildren2($list,$item['id'],$sike);
            if(!empty($children)) {
                 $menu['children'] = $children;
            }	
 	    $r[] = $menu;
         }
     }
     return $r;
}

结果5 出现了一个诡异的效果也就是子级也跑到和父级一个层级了这显然不是我们想要的结果

findChildren2 是我为了避免结果5 这种情况而进行改造了

下面是chatGPT 给出的说明

最终结果修改使用strcmp

function findChildren($list, $p_id){
        $r = array();
        foreach ($list as $k => $item) {
            //if ($item['fid'] == $p_id) {
            if (strcmp($item['fid'], $p_id) ===0 )  {
                unset($list[$k]);
                $length = count($r);
                $r[$length] = $item;
                if ($t = findChildren($list, $item['id'])) {
                    $r[$length]['children'] = $t;
                }
            }
        }
        return $r;
}

function findChildren2($list,$p_id,&$sike=[]) {
    $r = array();
    foreach($list as $k=>$item) {
         //if($item['fid']==$p_id && !isset($sike[$item['id']])) {
        if (strcmp($item['fid'], $p_id) ===0 )  {
            $menu = $item;
            //$sike[$item['id']] = true;
            $children = findChildren2($list,$item['id'],$sike);
            if(!empty($children)) {
                 $menu['children'] = $children;
            }
            $r[] = $menu;
         }
     }
     return $r;
}

使用该逻辑判断：if (strcmp($item['fid'], $p_id) === 0) {}

完美解决！！！！！
