在php循环中获取下拉框html的默认值

So I have this problem, which I don't see how it's happening. Basically I have 2 arrays one of which has a list of apparatus and the other just has one apparatus that the user can operate. I want to have a dropdown list of all the apparatus avliable, but the default value that is selected is the one that they can operate (They can only operate one at a time) Here is the code, and I have an if statement to check if the user can operate it and selected = "selected" but that doesn't seem to be working (In firefox)... Any help would be great.

Thanks!

 <?php
                            foreach ($apparatuslist as $apparatus):?>
                            <option value="<?php echo $apparatus['apparatus'];?>" <?php if ($driveron['apparatus'] == $apparatus['apparatus']){echo "SELECTED";} ?> ><?php echo substr($apparatus['apparatus'], 5); ?></option>


                            <?php endforeach;?>

    You have it right in your question, but not in your code

    <?php
        foreach ($apparatuslist as $apparatus):?>
        <option value="<?php echo $apparatus['apparatus'];?>" <?php if ($driveron['apparatus'] == $apparatus['apparatus']){echo "selected=\"selected\"";} ?> ><?php echo substr($apparatus['apparatus'], 5); ?></option>
    <?php endforeach;?>
    

    Should do the trick..
