    <p>This recursive function will add the given datum to the correct parent, and should be called once for each element in your starting array.</p> <pre><code>function add_branch(&amp;$tree, $datum, $parent) { // First we have the base cases: // If the parent is NULL then we don't need to look for the parent if ($parent == NULL) { $tree[$datum] = array(); return true; } // If the array we've been given is empty, we return false, no parent found in this branch if (! count($tree)) { return false; } // We loop through each element at this level of the tree... foreach($tree as $key =&gt; $val) { // If we find the parent datum... if ($key == $parent) { // We add the new array in and we're done. $tree[$key][$datum] = array(); return true; } // Otherwise, check all the child arrays else { // Now we check to see if the parent can be found in the curent branch // If a recursive call found a parent, we're done if (add_branch($tree[$key], $datum, $parent)) { return true; } } } // If none of the recursive calls found the parent, there's no match in this branch return false; } </code></pre> <p>The comments are quite verbose, in the hope that you can understand what is going on. I'd encourage you to do a bit of reading on recursive functions to get your head around it.</p> <p>This is how it would be used:</p> <pre><code>$arr = array( 0 =&gt; NULL, 1 =&gt; NULL, 2 =&gt; NULL, 3 =&gt; NULL, 8 =&gt; '2', 9 =&gt; '2', 10 =&gt; '2', 11 =&gt; '2', 12 =&gt; '3', 13 =&gt; '3', 14 =&gt; '8', 15 =&gt; '8', 16 =&gt; '14', 17 =&gt; '14', 18 =&gt; '14' ); $final = array(); foreach ($arr as $datum =&gt; $parent) { add_branch($final, $datum, $parent); } </code></pre> <p><code>$final</code> now has the correct finishing array, as indicated in the question.</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.
