What are some best practices for maintaining default values in select boxes when editing data?

When editing data in a form, it is important to maintain the default values in select boxes to ensure that the user does not inadvertently change the value. One way to achieve this is by populating the select box with the default options and setting the selected attribute for the option that matches the current value of the data being edited.

&lt;select name=&quot;category&quot;&gt;
    &lt;option value=&quot;1&quot; &lt;?php if($data[&#039;category&#039;] == 1) echo &#039;selected&#039;; ?&gt;&gt;Category 1&lt;/option&gt;
    &lt;option value=&quot;2&quot; &lt;?php if($data[&#039;category&#039;] == 2) echo &#039;selected&#039;; ?&gt;&gt;Category 2&lt;/option&gt;
    &lt;option value=&quot;3&quot; &lt;?php if($data[&#039;category&#039;] == 3) echo &#039;selected&#039;; ?&gt;&gt;Category 3&lt;/option&gt;
&lt;/select&gt;
