how to properly use switch function in php -


i want use switch function on value of radio button don't know how proper use it.

 if(isset($_post['itemtype']))     {     $itemtype = $_post["itemtype"];                              switch ($itemtype)     {     case "ingredient":     $brandname = $_post["brandname"];  if(isset($_post['brandname']))     {     $try2 = "brandname working";     }     else     {     $errormsg = 'error on branchname';     }     break;     case "miscellaneous":     $size = $_post["size"];     $color = $_post["color"];     if(isset($_post['size']))     {     $try2 = "misc working";     }     else     {     $errormsg = 'error on size';     break;     }   else { $errormsg = 'error5'; }

my bad on string part :) doesn't check if brandname set or null.

problem strings aren't inside quotes ex : case miscellaneous: should case "miscellaneous":
