php怎么取出每一个子数组里得值

<code>Array ( 
[0] => Array ( [stat_day] => 2014-07-24 [stat_type] => 1 [total] => 445 ) [1] => Array ( [stat_day] => 2014-07-21 [stat_type] => 2 [total] => 547 ) [2] => Array ( [stat_day] => 2014-07-23 [stat_type] => 2 [total] => 498 ) [3] => Array ( [stat_day] => 2014-07-27 [stat_type] => 2 [total] => 679 ) [4] => Array ( [stat_day] => 2014-07-22 [stat_type] => 3 [total] => 910 ) [5] => Array ( [stat_day] => 2014-07-25 [stat_type] => 3 [total] => 78 ) [6] => Array ( [stat_day] => 2014-07-26 [stat_type] => 3 [total] => 547 ) [7] => Array ( [stat_day] => 2014-07-28 [stat_type] => 3 [total] => 417 ) [8] => Array ( [stat_day] => 2014-07-29 [stat_type] => 3 [total] => 747 ) 
) 
</code>

回复内容：

<code>Array ( 
[0] => Array ( [stat_day] => 2014-07-24 [stat_type] => 1 [total] => 445 ) [1] => Array ( [stat_day] => 2014-07-21 [stat_type] => 2 [total] => 547 ) [2] => Array ( [stat_day] => 2014-07-23 [stat_type] => 2 [total] => 498 ) [3] => Array ( [stat_day] => 2014-07-27 [stat_type] => 2 [total] => 679 ) [4] => Array ( [stat_day] => 2014-07-22 [stat_type] => 3 [total] => 910 ) [5] => Array ( [stat_day] => 2014-07-25 [stat_type] => 3 [total] => 78 ) [6] => Array ( [stat_day] => 2014-07-26 [stat_type] => 3 [total] => 547 ) [7] => Array ( [stat_day] => 2014-07-28 [stat_type] => 3 [total] => 417 ) [8] => Array ( [stat_day] => 2014-07-29 [stat_type] => 3 [total] => 747 ) 
) 
</code>

一种思路就是用foreach遍历该数组，然后输出各个子数组里面的所有内容。
