<?php
$names = array("bob", "john", "colly", "sparky");
$options = array();
foreach ($names as $name) {
    $options[] = sprintf('<option value="%s"> %s </option>' , $name , $name);
}
?>

<select>
<?=implode("\n",$options);?>

</select>

Finally, one last way.
I prefer to make each string an item in an array.
Then implode that array into a single string.
JS would call that array.join instead of implode.
The "\n" inserts the invisible "new line" character
that pushes text onto new lines and makes the
"view source" look "neater" if you want it to be.
