打印数组多维php

Question

我有一个多维数组：

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

                        )

                )

        )

我需要去打印[0]和[1]的值，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...为什么不在数组 [1] 上循环？

Answer 1

你可以试试这个：

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

Answer 2

您需要 3 个嵌套的 for 循环。内部的将有键值对

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;
    }
  }
}
