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

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！！！！！
