What is the purpose of the "selected='selected'" attribute in HTML Select elements and how can it be dynamically set in PHP?

The "selected='selected'" attribute in HTML Select elements is used to pre-select an option within a dropdown menu. To dynamically set this attribute in PHP, you can use an if statement to check if the value of each option matches a variable, and if so, add the "selected" attribute to that option.

&lt;select name=&quot;dropdown&quot;&gt;
    &lt;option value=&quot;option1&quot; &lt;?php echo ($variable == &#039;option1&#039;) ? &#039;selected&#039; : &#039;&#039;; ?&gt;&gt;Option 1&lt;/option&gt;
    &lt;option value=&quot;option2&quot; &lt;?php echo ($variable == &#039;option2&#039;) ? &#039;selected&#039; : &#039;&#039;; ?&gt;&gt;Option 2&lt;/option&gt;
    &lt;option value=&quot;option3&quot; &lt;?php echo ($variable == &#039;option3&#039;) ? &#039;selected&#039; : &#039;&#039;; ?&gt;&gt;Option 3&lt;/option&gt;
&lt;/select&gt;
