Question

I have an idiot question but I’m stuck.

here is my simply code

$my_string = '00';

switch ((string)$my_string)
{
    case '-1': $return_string = 'bla bla..'; break;
    case '0': $return_string = 'One zero'; break;
    case '00': $return_string = 'Double zero'; break;
    default: $return_string = 'default'; break;
}

echo $return_string;

The result of the code before returns

One Zero

any suggestions ?

Well,
this is basically because php is not a strongly type language.
so “00” == “0” gives true (and as said switch uses the equality operator)

you might change this to if else statements with triple equals and that would do it.

“00” === “0” gives false. check this thread for more details. How do the PHP equality (== double equals) and identity (=== triple equals) comparison operators differ?
