09 function arr_foreach ($arr)
10 {
11     if (!is_array ($arr))
12     {
13         return false;
14     }
15      
16     foreach ($arr as $key => $val )
17     {
18         if (is_array ($val))
19         {
20             arr_foreach ($val);
21         }
22         else
23         {
24             echo $val.'<br/>';
25         }
26     }
27 }

29 $arr1 = array (1=>array(11,12,13,14=>array(141,142)),2,3,4,5);
30  
31 echo '<pre>';
32 print_r($arr1);
33 echo '<pre>';
34  
35 arr_foreach ($arr1);
36 ?>

程序运行结果为:

01 Array
02 (
03     [1] => Array
04         (
05             [0] => 11
06             [1] => 12
07             [2] => 13
08             [14] => Array
09                 (
10                     [0] => 141
11                     [1] => 142
12                 )
13  
14         )
15  
16     [2] => 2
17     [3] => 3
18     [4] => 4
19     [5] => 5
20 )
21 11
22 12
23 13
24 141
25 142
26 2
27 3
28 4
29 5
