    It's generally not acceptable to have a span inside the option tag, it's not valid html.

    Looking at your code you should apply a data attribute or a value to your options instead.

    For example,

    <p></p>
    <select id="eat" class="form-control">
    <?php foreach($foods as $key => $food) { ?>
        <option value="<?=$food['price'];?>"><?=$food['name'];?> - <?=$food['price'];?></option>
    <?php } ?>
    </select>
    
    <script>
    $("p").text($('#eat').val());
    </script>
