Are there any best practices for retrieving values from a database and setting them as predefined options in a <select> element?

When retrieving values from a database to set as predefined options in a <select> element, it is important to follow best practices to ensure security and efficiency. One common approach is to fetch the values from the database using a query, loop through the results to create <option> elements, and then output them within the <select> element. Additionally, it is recommended to sanitize the data to prevent SQL injection attacks. 

&lt;?php
// Assume $conn is the database connection

// Query to fetch values from the database
$sql = &quot;SELECT id, name FROM options_table&quot;;
$result = mysqli_query($conn, $sql);

// Check if query was successful
if ($result) {
    echo &quot;&lt;select name=&#039;options&#039;&gt;&quot;;
    while ($row = mysqli_fetch_assoc($result)) {
        echo &quot;&lt;option value=&#039;&quot; . $row[&#039;id&#039;] . &quot;&#039;&gt;&quot; . $row[&#039;name&#039;] . &quot;&lt;/option&gt;&quot;;
    }
    echo &quot;&lt;/select&gt;&quot;;
} else {
    echo &quot;Error fetching options from database&quot;;
}
?&gt;
