如何使用循环条件设置数组中所有元素的值？

I have an array listProduct. I want to loop through all element in this array and set condition itemID in listProduct is 0 will print a text.

Like this:

foreach (listProduct as $item)
   if($item->proCode == 0)
      echo "true";
   elseif ($item->proCode == 1)
      echo "false";
   else
      echo "nothing";
   endif

Problem is:

It will loop through this array, and this only compares the last item of an array with conditional.

If I add a break after echo command, it will fail at first element of an array.

I had a GUI when I clicked a button Edit. I want to check at this proCode is 0. It only loads any element, if proCode is 1, it loads another element.

Have any method to loop through sequence element in an array.

I think my question is unclear.

So, my case needs resolve with id. This mean, when to click an Edit button, get id to check in conditional.

Don't need any loop in this case.

Thanks, #FrayneKonok, #Barmar and #Abolarinstephen.

Try this:

The array must have an index 'proCode'

I am assuming this is a 2D array

$id = $_GET['id'];

if ($listProduct[$i]['proCode'] == 0):
    echo "True";
elseif ($listProduct[$i]['proCode'] == 1):
    echo "False";
 else:
     echo "Nothing";
 endif;
