这是数组打印出来的结果，在网上看到有把多维数组转化成一维数组的方法，但是这样循环遍历出来的结果只能通过下标来获取数据了
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

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

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？

$new_arr = array();
foreach ($result['respInfo']['userInfos'] as $k => $a) {
foreach ($a['userKeyInfos'] as $v) {
$new_arr[$k][$v['valueName']] = $v['value'];
}
}
print_r($new_arr);

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。
