HTML表单：在输入中显示文本（textarea）

Question

I have a form that I pre-fill with my database data. It is working perfectly for all my input. I have a text (that I enter in my database using a textarea). But when I am using the following the text does show in the text area (if I change it to input it is working but I do not have several lines and column allowed with textarea)

<textarea 
    rows="4"
    class="form-control" 
    name="roster_description" 
    id="roster_description" 
    placeholder =
        <?php if ($description_roster){
                echo '"'.$description_roster.'"'; 
            } else {
                echo "";
            }?>>
</textarea>

any ideas?

Just tested it and it works:

<textarea 
    rows="4"
    class="form-control" 
    name="roster_description" 
    id="roster_description" 
    placeholder = "<?php if ($description_roster) echo $description_roster;?>">
</textarea>
