Question

I have a simple html form with select element. To define which option is selected, I add selected as

<option value="10" <?php if($value == '10') {echo 'selected="selected"';}?>>10</option>
<option value="20" <?php if($value == '20') {echo 'selected="selected"';}?>>20</option>
<option value="50" <?php if($value == '50') {echo 'selected="selected"';}?>>50</option>

$value is a variable which comes from PHP codes. This methods seems to be very simple and naive. Is it the best way to do so?

Not a bad way to do it. But why not create the entire thing using programmatic approach (i.e., generate the code using a PHP loop through an array):

$items = array(10, 20, 50);
for ($i = 0; $i < count($items); $i ++) {
    echo("<option value='" . $items[$i] . "'");
    if ($items[$i] === $value) {
        echo(" selected='selected'");
    }
    echo(">" . $items[$i] . "</option>");
}
