<?php  } ?> 

but now listing morethan onetime(look uploaded image)

how i can change listing value display ones.?

Either do the foreach over possible values, and check whether the value is in selected values (only one option tag in your code then since you'r printing it in a loop):

<?php   foreach ($possibleValues as $possibleValue)

{?>   
<option <?php
    if($selectedValues[$possibleValue->id]){ echo ' selected="selected"'; } 
?> value="<?php
    echo $possibleValue->id
?>" ><?php
    echo $possibleValue->description
?></option>
<?php  } ?> 

Or print them as you do, but then don't use a for loop to print them - use a loop or better an associative array to check whether each of them is selected.
