Here's a small snippet showing how it works, I hope:

foreach ($DPRpriority as $item => $value) {
   echo "<li> ".$item.": ".$value['name']." selected:
".$value['selected']." </li>\n";

Question 1: when did we have to add [] to a <input> name to turn it into an array?

<input type="checkbox" name="DPRlocationdetails[]" value="Unknown">

According to phpinfo() it still comes out as $_POST['DPRlocationdetails'] without [].

Are the [] necessary?
Question 2:
I was looking at some code in the Manual, where someone used isset and is_array.

How necessary is if(isset($_POST['DPRlocationdetails']))

and then to use: if(is_array($_POST['DPRlocationdetails']))

That seems like over kill?
Question 3:

My code works, perfectly. In this case, I decided to attack some check-boxes first. The resulting function will work for <select multiple> too..

Does anyone see me doing something wrong in my code below?

My questions are:

Is this the only way to pass "Unknown", "Family Home" or "Apartment" into the function?

Is this correct?

---- if ($_POST['DPRlocationdetails'] == "Unknown")

Somebody once told me I had to do it this way?

---- if ("Unknown" == $_POST['DPRlocationdetails'])



<form action="foo.php" id="DPRform" method="post"><input value="Update" type="submit"> <input type="checkbox" name="DPRlocationdetails[]" value="Unknown" <?php filter_value($_POST['DPRlocationdetails'],"Unknown"); ?>> Unknown <input type="checkbox" name="DPRlocationdetails[]" value="Family Home" <?php filter_value($_POST['DPRlocationdetails'],"Family Home"); ?>> Family Home <input type="checkbox" name="DPRlocationdetails[]" value="Apartment" <?php filter_value($_POST['DPRlocationdetails'],"Apartment"); ?>> Apartment

function filter_value($tofilter,$tofind) {
foreach($tofilter as $value){
    if ($value == $tofind) echo "checked";
