Interesting -- is the casting to string type necessary there? I
haven't done that before, and it seems to have worked ok...
Depends whether you want strings or not. $book->name is a
SimpleXMLElement object, so if you want the string value it needs to
be cast to a string. This will be implicitly done if you use the
variable where PHP would expect a string, but in the name of
defensive programming I always cast XML values to the type I expect/
want them to be.
Remove the casts in that snippet and run it - you'll see the
variables are not strings.
Ah, thanks for that information. I guess I have just been lucky so
far. I will update my code and my style there to make it more accurate
and defensible.
