Get the Selected value from the Drop down box in PHP
<p>I am populating a Drop Down Box using the following code.</p>

<pre><code>&lt;select id="select_catalog"&gt;
&lt;?php 
$array_all_catalogs = $db-&gt;get_all_catalogs();
foreach($array_all_catalogs as $array_catalog){?&gt;
&lt;option value="&lt;?= $array_catalog['catalog_key'] ?&gt;"&gt;&lt;?= array_catalog['catalog_name'] ?&gt;&lt;/option&gt;  
</code></pre>

       

<p>Now how can I get the selected option value using PHP (I have the code to get the selected item using javascript and jquery) because I want the selected value to perform a query in database.</p>

<p>Any help will be much appreciated. Thank you very much...   </p>
