Is it necessary to execute the SELECT statement to query the database for data every time a <SELECT> element is used in HTML?

When using a <SELECT> element in HTML, it is not necessary to execute a SELECT statement every time the element is used. Instead, you can retrieve the data from the database once and store it in an array or variable. Then, you can use this array or variable to populate the <SELECT> element whenever it is needed. 

&lt;?php
// Connect to database and retrieve data
$connection = new mysqli(&#039;localhost&#039;, &#039;username&#039;, &#039;password&#039;, &#039;database&#039;);
$query = &quot;SELECT id, name FROM table&quot;;
$result = $connection-&gt;query($query);

// Store data in an array
$options = array();
while ($row = $result-&gt;fetch_assoc()) {
    $options[$row[&#039;id&#039;]] = $row[&#039;name&#039;];
}

// Populate &lt;SELECT&gt; element
echo &#039;&lt;select&gt;&#039;;
foreach ($options as $id =&gt; $name) {
    echo &#039;&lt;option value=&quot;&#039; . $id . &#039;&quot;&gt;&#039; . $name . &#039;&lt;/option&gt;&#039;;
}
echo &#039;&lt;/select&gt;&#039;;

// Close database connection
$connection-&gt;close();
?&gt;
