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

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

Array(    [0] => Array        (            [sdkUserPriId] => 100000124            [nickName] => 张尼玛            [head] => [   {      "bigKey" : "",      "bigUrl" : "group2/M00/00/05/wKgBC1TAV06BS21_AABoZKLBGRM281.png",      "smallKey" : "",      "smallUrl" : "group2/M00/00/05/wKgBC1TAV07RoHGEAAAXAgS_rVM330.png"   }]            [gender] => 1            [lastUpdateTime] => 0            [servercode] => 2        )    [1] => Array        (            [sdkUserPriId] => 100000125            [nickName] => 100000125            [head] => [   {      "bigKey" : "",      "bigUrl" : "group1/M00/00/1D/wKgBeVUTdUCRpZD9AAF6ty8lLh4759.png",      "smallKey" : "",      "smallUrl" : "group1/M00/00/1D/wKgBeVUTdUDyBV08AAAKBhUiAA8391.png"   }]            [gender] => 0            [lastUpdateTime] => 0            [servercode] =>         )

现在的问题是head字段里面的头像图片怎么取呢在我的foreach遍历里面加还是取出$new_arr再去遍历呢，servercode这个是区服也是在遍历里面做循环吗？

已经解决了。
