回显多维数组

Echo a multi dimensional array(回显多维数组)

问题描述

我有一个《使命召唤 4》玩家列表的多维数组.当我尝试回显该数组时，它返回 Array 30 次，因为服务器中有 30 个当前玩家.

I have an multidimensional array of a player list for Call of Duty 4. When I try to echo the array it comes back with Array 30 times because there are 30 current players in the server.

$promodplist 的 Var_Dump(玩家列表)

Var_Dump of $promodplist (Players List)

array(27) { 
    [0]=> array(6) { 
        ["frags"]=> string(1) "0" 
        ["ping"]=> string(2) "26"
        ["nick"]=> string(10) "DIVINEBRAH"
        ["gq_name"]=> string(10) "DIVINEBRAH"
        ["gq_score"]=> string(1) "0"
        ["gq_ping"]=> string(2) "26" 
    }
    [1]=> array(6) {
        ["frags"]=> string(1) "0" 
        ["ping"]=> string(2) "35" 
        ["nick"]=> string(7) "><> <><" 
        ["gq_name"]=> string(7) "><> <><" 
        ["gq_score"]=> string(1) "0" 
        ["gq_ping"]=> string(2) "35" 
    } 
    [2]=> array(6) { 
        ["frags"]=> string(1) "0" 
        ["ping"]=> string(2) "42" 
        ["nick"]=> string(10) "xXthe0neXx" 
        ["gq_name"]=> string(10) "xXthe0neXx" 
        ["gq_score"]=> string(1) "0" 
        ["gq_ping"]=> string(2) "42" 
    }

$servers['promod'] = array('cod4', '67.202.102.224');
$servers['promod2'] = array('cod4', '67.202.102.224');
$gq = new GameQ();
$gq->addServers($servers);
$results = $gq->requestData();
function print_results($results) {
foreach ($results as $id => $data)

这就是我试图用来列出当前球员的内容.

And this is what I am trying to use to list the current players.

$promodplist = $data['promod']['players'];
foreach($promodplist as $k => $v)

我只是想回显每个数组中的 nick(昵称).

I just simply want to echo out the nick (nickname) in each array.

推荐答案

$promodplist = $data['promod']['players'];
foreach($promodplist as $k => $v)
    print($v['nick']);

应该做你想做的.foreach 遍历数组中的键/值对，其中 $k 是元素的键(在您的情况下是基于 0 的索引)，而 $v 是值(玩家数据的数组，对于您而言).您可以通过使用其名称作为 数组访问器.

Should do what you want. foreach iterates through the key/value pairs in the array, where $k is the element's key (a 0-based index, in your case) and $v is the value (an array of player data, for you). You can access the rest of the information by using its name as the key in the array accessor.
