  this if statement is false, because $a == 1

                        $b = 1;

                        $id = "a";

                  
            }

this if statement is true, because $b has not been defined, and is evaluating to 0

            elseif ($b == 0) {

                  
                        $c = 1;

                        $id = "b";

                  
            }

this statement never gets reached, because the previous statement was true

            elseif ($c == 0){

                  
                        $d = 1;

                        $id = "c";

                  
            }

echo "ID = $id<br>"; //Output is "b"...WHY?? It should be "outside"... ?>
