    <p>I have an array consisting of many other arrays, which might also consist of other arrays. Its basically like a navigation hierarchy, one menu link can be a menu with sub menus and so on.</p> <p>The structure of <code>$mainarray</code> is like this:</p> <pre><code>'childarray1' =&gt; array( 'link' =&gt; array( .. 'mykey' =&gt; 'valueofinterest' ), 'below' =&gt; array() of childarrays ), 'childarray2' =&gt; array( 'link' =&gt; array( .. 'mykey' =&gt; 'somevalue' ) ), 'childarray3' =&gt; array( 'link' =&gt; array( .. 'mykey' =&gt; 'someothervalue' ), 'below' =&gt; array() of childarrays ) </code></pre> <p>Each <code>childarray</code> can have 2 direct child <code>keys</code>, <code>'links'</code> and optionally <code>'below'</code>. Within <code>links</code> there is always a <code>key 'mykey'</code>, which is the only key that I need to check. If a child array has <code>['links']['mykey'] == 'valueofinterest'</code>, <strong>I'd like to have this element returned</strong>, like <code>$sub = $mainarray['child1']['below']['child11']['below']['childofinterest']</code>.<br> <code>'below'</code> means that the childarray has childs itself which can also have below arrays (sub menu..).</p> <p>My hude problem is that the childarray I try to find can be in any other childarrays'S <code>'below'</code> key, I dont know the depth (its not too deep, though it can vary). I've tried to mess with foreach loops and while loops and combining those, I just cant figure it out how to get the child array. I want to do it like this:</p> <pre><code>$value = 'xxx'; $sub = return_sub_menu($value); function return_sub_menu($value) { $array = $mainarray(); $sub = array(); // find the child array which's ['link']['mykey'] == $value; // $sub is now something like: // 'childarray321' =&gt; array( // 'link' =&gt; array( // .. // 'mykey' =&gt; 'xxx' // ), // 'below' =&gt; array() of childarrays which i NEEED :) // // ) return $sub; } </code></pre> <p>I've tried to walk recursively but cant figure out how to return the element :(</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
