如何选择下一个数组键

Question

$result =   
  Array
  (
   [kpi] => calls
   [team] => team1
   [content] => Array
     (
        [0] => Array
            (
                [name] => June
                [last_name] => Fernandez
                [user_name] => junef
                [result] => 19
            )
        [1] => Array
            (
                [name] => Juan
                [last_name] => Fernandez
                [user_name] => juanf
                [result] => 19
            )
    )

  Array
  (
   [kpi] => emails
   [team] => team2
   [content] => Array
     (
        [0] => Array
            (
                [name] => May
                [last_name] => Fernandez
                [user_name] => mayf
                [result] => 19
            )
        [1] => Array
            (
                [name] => July
                [last_name] => Fernandez
                [user_name] => july
                [result] => 19
            )
    )

//////

foreach($result as $teams){
  print_r(next($teams));
}

什么都不返回 在每个循环中，我想选择数组的下一个键和值。

Answer 1

只需使用索引

foreach ($result as $i => $teams) {
  if ($i+1 < count($result)) {
    print_r($result[$i+1]);
  }
}

Answer 2

<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport);    // $mode = 'bike';
$mode = next($transport);    // $mode = 'car';
$mode = prev($transport);    // $mode = 'bike';
$mode = end($transport);     // $mode = 'plane';
?>
