php递归数组扁平处理

php递归数组扁平处理

如何将一个递归数组，就是带有层级显示的数组转换成同一层级

比如一个数组是一个树型，如何转换成一个二维数组

以下为代码

```
public function ssb($aa){
$sb = array();
foreach($aa as $v){
$arr = array();
$arr['title'] = $v['title'];
$arr['id'] = $v['id'];
$arr["pid"] = $v['pid'];
$arr["icon"] = $v['icon'];
$arr["path"] = $v['path'];
$arr["component"] = $v['component'];
$arr["level"] = $v['level'];
$arr["params"] = $v['params'];
$arr["url"] = $v['url'];
$sb[] = $arr;
if(isset($v['child'])){
$sbb = $this->ssb($v['children']);
$sb = array_merge($sb,$sbb);
}
}
return $sb;
}

//验证token
public function verifyToken(Request $request)
{
$param = $request->all();
// $header = $request->header();
$header = ['Authorization:'.$request->header('Authorization')];
$res = ZtService::callCoreApi('account', 'staff/getTokenInfo',$param,$header);
$menu = $res['menu'];
if(is_array($menu) && count($menu) > 0){
foreach($menu as $key=>$value){
$lis = array();
$liss['id'] = $value['id'];
$liss['title'] = $value['title'];
$liss["pid"] = $value['pid'];
$liss["icon"] = $value['icon'];
$liss["path"] = $value['path'];
$liss["component"] = $value['component'];
$liss["level"] = $value['level'];
$liss["params"] = $value['params'];
$liss["url"] = $value['url'];
//分解最终用$lis[]存储
$lis[] = $liss;
if(isset($value['children'])){
$li = $this->ssb($value['children']);
$lis = array_merge($lis,$li);
}
$result[] = $lis;
}
foreach($result as $kk=>$vv){
foreach($vv as $kkk=>$vvv){
$test[] = $vvv;
}
}
$res['all_menu'] = $test;
}
return $this->jsonData($res);
}

```
