• String::New: what is it?

  - by JavaMan

  I am from a Java background and is learning C++. I encountered the following C++ code: String source = String::New("'Hello' + ', World'"); As what I understand so far, this should be a call to static member function 'New' of class 'String'. But, I've searched through the whole header file defining 'String', there is not any static member named 'New' in the String class or its super classes. Is there any special meaning attached to String class or the New member function in C++?

• [PHP] Dots and spaces in variable names from external sources are converted to underscores

  - by Brandon

  Trying a bit of AJAX, and I find that much of my data is littered with underscores! Documentation confirms that this is working as intended. Any way to pass my form information to PHP in tact? I'm using code igniter, so my pass looks like /controller/function/variable, receiving controller: controller{ function($v=0){#what once was hello world is now hello_world...} } I can't very well do an undo, data might contain an underscore. Thanks, Brandon
