PHP assoc array, get max number of items
<p>I've got an array looking something like this:</p>

<pre><code>Array
(
    [A] =&gt; Array
        (
            [A] =&gt; Array
                (
                    [01] =&gt; Array
                        (
                            [01] =&gt; Array
                                (
                                    [0] =&gt; 01
                                    [1] =&gt; 02
                                )

                            [02] =&gt; Array
                                (
                                    [0] =&gt; 01
                                    [1] =&gt; 02
                                    [2] =&gt; 03
                                    [3] =&gt; 04
                                    [4] =&gt; 05
                                )
</code></pre>

<p>I'm looking at the last level array, ie: ['A']['A']['01']['01']x and ['A']['A']['01']['02']x</p>

<p>At this level, in the example above, 01 has 2 items, 02 has 5 items, 03 could have 4 items, etc</p>

<p>I want to know, without iterating through all the items, what is the highest number of items, ie: in this example the highest number of items is 5 (not the value 05, but the number of items at this level of the array)</p>
