    <p>I have some functions that deal with data provided in array format. These functions all do the same job, so I would like to merge them into a single function.</p> <p>The problem is, each of them receives arrays with different depths: one-, two- and three-dimensional arrays are used and, in some future implementations, even four-dimensional arrays may be used.</p> <p>In any case, the significant and necessary data are always in the two innermost arrays, so I need to get rid of the outer arrays until I have only the innermost two-levels. My doubt is not simply how to do it, but how to do it elegantly and efficiently, as I find my current method rather clumsy.</p> <p>Current method:</p> <pre><code>function add() { $data = func_get_args(); if(count($data)&gt;0) { if(is_array($data[0])) { if(is_array($data[0][0])) { foreach($data[0] as $row) { $this-&gt;items[] = $row; } } else { $this-&gt;items[] = $data[0]; } } else { $this-&gt;items[] = $data; } } } </code></pre> <p>Some use examples:</p> <pre><code>$list-&gt;add('one', 'two', 'three', 'four', 'five'); $list-&gt;add($data_from_DB_in_array_format); $list-&gt;add( array( array('one', 'two', 'three', 'four', 'five'), array('six', 'seven', 'eight', 'nine', 'ten') ) ); $list-&gt;add( array( array( array('one', 'two', 'three', 'four', 'five'), array('six', 'seven', 'eight', 'nine', 'ten') ) ) ); </code></pre> <p>As the data is recovered via func_get_args(), everything is put inside an extra array.</p> <p>The result must be something like this:</p> <pre><code> array( array('one', 'two', 'three', 'four', 'five'), array('six', 'seven', 'eight', 'nine', 'ten') ); </code></pre>

    3. COThe func_get_args() is needed because in one instance the data is passed not as an array but as list with a varying quantity of elements.

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.
