PHP如何回显3-Dim数组

Question

After searching for an answer in this forum I found only related questions but under other context that would not apply to my case. Here's my problem:

I have a 3-dim array defined in a function like this:

$m_Array[h][$family][$iterator]

the values for

$family range from 6-10;

$iterator from 0-3 but has duplicates (0,1,2,3,1),

and the  $m_Array results in values (25,26,30,31,33).

I am unable to echo the result using those indices to get these results once returned from the function. NOTE: I was able to echo when I had 2-dim $m_Array[h][$iterator] but could not use it because the last value for the iterator would replace the second in the array. Since I was able to echo the 2-dim, this is not a question on getting the return from the function or iterate over the indices. Thanks.

as others mentioned, you can use var_dump() or print_r(). If you need to access each item then you're going to need nested loops.

foreach($m_Array as $i => $h)
{
     //echo $i, $key for h
     foreach($h as $j => $family)
     {
          //echo $j, key for family
          foreach($family as $k => $iterator)
          {
                echo $iterator;
          }
     }
}
