function arr_foreach ($arr) { static $data; if (!is_array ($arr)) { return $data; } foreach ($arr as $key => $val ) { if (is_array ($val)) { arr_foreach ($val); } else { //$data[$key]=$val; $data[] = $val; } } return $data; } $res=arr_foreach($result ); print_r($res); 尝试过在 $data[] = $val;里面加上key但是获取的信息就不全了。$result返回来的可能是多条用户信息，打印只打印了单条出来，其他的结构都是一样的。求帮忙
回复讨论(解决方案)
求帮帮忙，发现一个问题，就是这个方法遍历的时候，如果返回的是多个用户的，它全都在一个array里面显示了，id跟着往下走的。
没人嘛，技术大大呢。
你这是一个4维以上的数组，你打算做什么呢？
按你示例的代码，输出的是一维数组。需求是这样吗？

嗯，就是转化成一维之后发现如果用户数据有多条的话，他的下标就会一直增加，没办法去循环遍历了，我现在想做的就是查询出10个用户数据，然后获取到用户名字、区服、头像、性别列表显示出来。不知道怎么来写循环
你是要取 userKeyInfos 键下的内容吗？
如果要代码，请给出原始数组的 var_export 打印结果

$new_arr = array(); foreach ($result['respInfo']['userInfos'] as $k => $a) { foreach ($a['userKeyInfos'] as $v) { $new_arr[$k][$v['valueName']] = $v['value']; } } print_r($new_arr); 这个是捣腾出来遍历的结果

已经解决了。
