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.'<br/>';
        }
    }
}

$arr1 = array (1=>array(11,12,13,14=>array(141,142)),2,3,4,5);

echo '<pre>';
print_r($arr1);
echo '<pre>';

arr_foreach ($arr1);
?>

程序运行结果为：

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
