    <p>I have an array like</p> <pre><code> Array ( [0] =&gt; Array ( [id] =&gt; 81 [cata_key] =&gt; 908cbbcb86a1cf64b67c96ff [cata_name] =&gt; Lunch [app_key] =&gt; 2fabc0d9447c6375657dead4 [parentid] =&gt; 0 [subcategories] =&gt; Array ( ) ) [1] =&gt; Array ( [id] =&gt; 80 [cata_key] =&gt; baac98b4e73c05ebbf45bdc6 [cata_name] =&gt; Break Fast [app_key] =&gt; 2fabc0d9447c6375657dead4 [parentid] =&gt; 0 [subcategories] =&gt; Array ( [0] =&gt; Array ( [id] =&gt; 82 [cata_key] =&gt; 5970b7afc450ef3b24573de9 [cata_name] =&gt; Rise Products [app_key] =&gt; 2fabc0d9447c6375657dead4 [parentid] =&gt; 80 [subcategories] =&gt; Array ( [0] =&gt; Array ( [id] =&gt; 83 [cata_key] =&gt; 82e36d8f821e14fc8db1d4da [cata_name] =&gt; Dosha [app_key] =&gt; 2fabc0d9447c6375657dead4 [parentid] =&gt; 82 [subcategories] =&gt; Array ( [0] =&gt; Array ( [id] =&gt; 84 [cata_key] =&gt; 49730020d850439dd7de8747 [cata_name] =&gt; Masala Dosha [app_key] =&gt; 2fabc0d9447c6375657dead4 [parentid] =&gt; 83 [subcategories] =&gt; Array ( ) ) ) ) ) ) ) ) ) </code></pre> <p>I would like to find the depth of the root indexed sub array from a particular inner array id. For example I would like to find the depth of the root indexed array from the parentid=0, it should be 1. The depth of the root indexed sub array from the parentId=0/80/82/83 should be 4. </p> <p>Actually my aim is to limit the depth of an array. There should a depth limit. So when any one try to add a sub array to this array , we should find out the current array depth . For example the array depth limit is 4 , and any one try to add a sub array under cata_name= Masala Dosha, the depth already reached and should not allow to add new sub array. But at the same time he can add a sub array under [cata_name] => Lunch, because its depth is only 1 and the depth limit is 4. </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.
