    <p>I'm trying to get an item of an array by its key. The array is in fact a SolrObject, which implements ArrayAccess, so I understand that I can access its items as I would in an array.</p> <p>This is the structure of my $myobject:</p> <pre><code>SolrObject Object ( [116809] =&gt; SolrObject Object ( [title] =&gt; Array ( [0] =&gt; First value ) [description] =&gt; Array ( [0] =&gt; Second value ) ) [591978] =&gt; SolrObject Object ( [title] =&gt; Array ( [0] =&gt; Third value ) [description] =&gt; Array ( [0] =&gt; Forth value ) ) ) </code></pre> <p>So, if I try</p> <pre><code>var_dump($myobject[116809]); </code></pre> <p>I get NULL.</p> <p>But if I try</p> <pre><code>echo array_key_exists(116809, $myobject); </code></pre> <p>I get <strong>1</strong></p> <p>If I try to iterate $myobject with a foreach, I can access its elements correctly.</p> <p><strong>Why can't I access directly one element by its key?</strong></p> <p><strong>EDIT:</strong> Answering to @ircmaxell, this is the var_dump:</p> <pre><code>object(SolrObject)#219 (50) { [116809]=&gt; object(SolrObject)#220 (2) { ["title"]=&gt; array(1) { [0]=&gt; string(43) "First value" } ["description"]=&gt; array(1) { [0]=&gt; string(82) "Second value" } } [591978]=&gt; object(SolrObject)#221 (2) { ["title"]=&gt; array(1) { [0]=&gt; string(104) "Third value" } ["description"]=&gt; array(1) { [0]=&gt; string(95) "Fourth value" } } } </code></pre> <p>And this is the result of var_dump($myobject->getPropertyNames());</p> <pre><code>array(2) { [0]=&gt; string(0) "" [1]=&gt; string(0) "" } </code></pre>

    1. COI know, but this object implements ArrayAccess. How could I achieve what I need?

    2. COIt's the offsetGet method that is invoked when you do something like $solr['xyz']. Have you tried calling that method directly for testing purposes?

    3. CO@Russell: Yes you can. If the object implements `ArrayAccess`, it does allow you to access the object like an array. @David: As far as this issue goes, try testing with `isset($myobject[116809])`. Also, show a `var_dump($myobject)`. I have a feeling the base object is not of `SolrObject`... I could be wrong, but looking at the docs, it appears like it should be different...

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.
