    <p>I have an array of objects, but I need to remove a similar objects by a few properties from them:</p> <p>for example:</p> <pre><code>array(12) { [0]=&gt; object(stdClass)#848 (5) { ["variant"]=&gt; object(stdClass)#849 (4) { ["name"]=&gt; string(8) "Alex" } ["age"]=&gt; int(10) } [1]=&gt; object(stdClass)#851 (5) { ["variant"]=&gt; object(stdClass)#852 (4) { ["name"]=&gt; string(8) "Alex" } ["age"]=&gt; int(10) } </code></pre> <p>How to make a one object in array for this ( if for example I need to compare only by a name property? )</p> <p>Still have an issue with it.</p> <p><strong>Updated</strong></p> <p>I've create a new array of objects:</p> <pre><code>$objects = array( (object)array('name'=&gt;'Stiven','age'=&gt;25,'variant'=&gt;(object)array('surname'=&gt;'Sigal')), (object)array('name'=&gt;'Michael','age'=&gt;30,'variant'=&gt;(object)array('surname'=&gt;'Jackson')), (object)array('name'=&gt;'Brad','age'=&gt;35,'variant'=&gt;(object)array('surname'=&gt;'Pit')), (object)array('name'=&gt;'Jolie','age'=&gt;35,'variant'=&gt;(object)array('surname'=&gt;'Pit')), ); echo "&lt;pre&gt;"; print_r($objects); </code></pre> <p>So what I need to do is to compare an object properties (variant->surnames and ages), if two objects has a similar age and variant->surname we need to remove the one of these objects.</p> <p>A half of <code>solution</code> is:</p> <pre><code>$tmp = array(); foreach ($objects as $item=&gt;$object) { $tmp[$object-&gt;variant-&gt;surname][$object-&gt;age] = $object; } print_r($tmp); </code></pre> <p>Unfortunatelly I need an old-style array of objects.</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.
