How can a select dropdown in HTML be properly implemented to ensure valid HTML syntax and functionality in PHP?

To properly implement a select dropdown in HTML to ensure valid syntax and functionality in PHP, you need to use the <select> tag for the dropdown menu and <option> tags for each selectable item within the dropdown. Make sure to include a name attribute for the select element so that the selected option can be passed to the PHP script. Here is an example of how to implement a select dropdown in PHP: 

&lt;form method=&quot;post&quot; action=&quot;process_form.php&quot;&gt;
    &lt;select name=&quot;dropdown&quot;&gt;
        &lt;option value=&quot;option1&quot;&gt;Option 1&lt;/option&gt;
        &lt;option value=&quot;option2&quot;&gt;Option 2&lt;/option&gt;
        &lt;option value=&quot;option3&quot;&gt;Option 3&lt;/option&gt;
    &lt;/select&gt;
    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
&lt;/form&gt;
