I have a snippet of code:

PHP Code:
switch (id)
{
    case 1:
        doFunction(parameter1);
        break;
    case 2:
        doFunction(parameter2);
        break;
    case 3:
        doFunction(parameter3);
        break;
    default:
        document.write('Error: '+id);
} 
The strange thing is that the document says, "Error: 3". If the variable id is equal to 3, then why didn't the switch statement go through case 3? I must have something confused.

Help anyone?
