我有一个多维数组：

 Array
(
    [account] => Array
        (
            [0] => Array

                        )

                )

        )

我需要去打印[0]和[1]的值，而foreach只打印[0]的值。

//the foreach 
<?php 
foreach($real as $r => $val){ 
echo $val['id'];
echo $val['name'];
echo $val['accountId'];
echo $val['gain'];
echo $val['daily'];
echo $val['monthly'];
echo $val['balance'];

?>

这个foreach只打印[0]的值......为什么不循环遍历数组[1]？

Answer 1

你可以试试这个：

foreach($data['account'] as $key=>$val){
    echo $val['id'];
    echo $val['name'];
}

Answer 2

你需要3个嵌套for循环。内部的一个将具有键值对

如果$ a是你的变量名，那么

foreach($a as $b)
{
  foreach($b as $val)
  {
    foreach($val as $key=>$vl)
    {
      echo $key.' '. $vl;
    }
  }
}
