在php中数组分类很多种，如一维数组，二维数组，三维或多维数组，下面我来给大家介绍php 遍历多维数组，有需要的朋友可参考。

在php遍历数组有三个函数foreach、each、list & each下面我们看它们是如何遍历多维数组的。

先看一个遍历二维数组

代码如下	复制代码
$sports = array( 'football' => 'good', 'swimming' => 'very well', 'running' => 'not good' ); foreach ($sports as $key => $value) { echo $key.": ".$value." "; } ?>

下面看遍历三维数组

例1

代码如下	复制代码
function arr_fun($arr){ if(is_array($arr)){ foreach($arr as $v){ if(is_array($v)){ arr_fun($v); }else{ echo $v." "; } } }else{ echo $arr." "; } }

例2

代码如下

复制代码

/*
* -------------------------------------------------
*   Url    : www.bKjia.c0m
*   Date   : 2011-03-09
* -------------------------------------------------
*/
function arr_foreach ($arr)
{
if (!is_array ($arr))
{
  return false;
}

foreach ($arr as $key => $val )
{
  if (is_array ($val))
  {
   arr_foreach ($val);
  }
  else
  {
   echo $val.'
';
  }
}
}
$arr1 = array (1=>array(11,12,13,14=>array(141,142)),2,3,4,5);
echo '

';

print_r($arr1);

echo '';

arr_foreach ($arr1);

?>
输出结果
Array

(

    [1] => Array

        (

            [0] => 11

            [1] => 12

            [2] => 13

            [14] => Array

                (

                    [0] => 141

                    [1] => 142

                )

        )

    [2] => 2

    [3] => 3

    [4] => 4

    [5] => 5

)

11

12

13

141

142

2

3

4

5

利用list与each遍历二维数组

代码如下

复制代码

$sports = array(
    'football' => 'good',
    'swimming' => 'www.bKjia.c0m',
    'running' => 'not good'
);

while (list($key, $value) = each($sports)) {
echo $key.": ".$value."
";
}
?>
