Prevent direct access to a php include file

Convert List to List
... not really "true". The simple answer is that C# doesn't support this. The idea of having a list of animals that contains giraffes and tigers is perfectly valid. The only issue comes when you want to access the higher level classes. In reality this is no different to passing a parent class as a para...

...about the getattr() function . The problem is that I still can't grasp the idea of its usage. The only thing I understand about getattr() is that getattr(li, "pop") is the same as calling li.pop .

Multiple constructors in python? [duplicate]
...likes this approach). This is just a silly example, but I hope you get the idea:
class C(object):
def __init__(self, fd):
# Assume fd is a file-like object.

...ependent to some degree, so it might not be cross-browser compatible.
The idea is to parse the parameter names from the string representation of the function so that you can associate the properties of an object with the corresponding parameter.
A function call could then look like
func(a, b, {so...

public class DataHolder {
private static String data;
public static String getData() {return data;}
public static voi...
How can I “unuse” a namespace?

In general, this is a terrible idea. C++ headers are not intended to be included in an alternately namespace as was used here.
