It's just something that crops up every now and again. E.g. when you take
it from an array or something like that.

Should be the normal casting behavior.

zendi_convert_to_long() isn't really what I'm looking for. All the current
convert functions convert a zval, which is not what you normally need, at
least that's the feeling that I got. So what you end up doing is something
like this:
long result;
Z_ADDREF_P(zval);
convert_to_long_ex(&zval);
result = Z_LVAL_P(zval);
zval_ptr_dtor(&zval);
Which seems overly complicated to me. What I'm looking for is something
like this:
long result = zval_get_long_with_cast(zval);
Or maybe I'm missing something about how to easily get an integer from a
value?
