我只需要取出所有 ip（键“ip”的值）并将它们放入普通数组中，如 ips[]

我已经尝试了一些东西，但是自从我使用php以来已经很久了，它没有出现，任何帮助都很棒！

$ips = array_map(function($i) { return $i['ip']; }, $arr['routingTable']);

如果您没有 php >= 5.3 - 只需使用普通旧foreach版本并手动收集数据

使用 zerkms 答案，但对于 PHP < 5.3：

$i=-1;
foreach($arr['routingTable'] as $a){
 $i++;
 $ips[] = $a[$i]['ip'];
}
