• Is session destory not enough to clean the session

  - by Kamo

  When the user clicks a logout button, I connect to a script that simply does this session_destroy(); session_start(); I thought this would be enough to reset all $_SESSION variables such as $_SESSION['logged'] and $_SESSION['username'] but when I load the page again, it automatically logs me in as if the session is still active.

• why do I need the @ for setting variable value

  - by Saad

  I'm a little confused about scope of variables, in ruby I wrote a test program: class Test attr_reader :tester def initialize(data) @tester = data end def getData tester end end puts Test.new(11).getData now this works fine, the attr_reader, but my confusion is that since I've define attr_reader :tester then why can't I go tester = data rather then @tester = data, because when retrieving the data in getData I only have to write tester and not @tester

• Why is it that I can include a header file in multiple cpp files that contains const int and not have a compiler error?

  - by tree

  Let's assume that I have files a.cpp b.cpp and file c.h. Both of the cpp files include the c.h file. The header file contains a bunch of const int definitions and when I compile them I get no errors and yet I can access those const as if they were global variables. So the question, why don't I get any compilation errors if I have multiple const definitions as well as these const int's having global-like scope?

• PHP Beginner: How to pass PHP variable from one PHP code segment to another ?

  - by Misha Moroshko

  I have index.php which uploads a file to server and sets several PHP variables (like $target_folder_and_file_name). index.php also has the following line (it was originally index.html): <script language="JavaScript" src="main.js.php"></script> After index.php returned to the browser, the browsers asks for main.js.php from the server (right?). Can I access somehow $target_folder_and_file_name from the PHP code in main.js.php ?

• Pickling a class definition

  - by Giorgio

  Is there a way to pickle a class definition? What I'd like to do is pickle the definition (which may created dynamically), and then send it over a TCP connection so that an instance can be created on the other end. I understand that there may be dependencies, like modules and global variables that the class relies on. I'd like to bundle these in the pickling process as well, but I'm not concerned about automatically detecting the dependencies because it's okay if the onus is on the user to specify them.

• What is a de-compiler how does it work?

  - by thyrgle

  So is a decompiler really a thing that gives gives the source of a compiled/interpreted piece of code? Because to me that sounds impossible. How would you get the names of the functions, variables, classes, etc if it is compiled. Or am I misinterpreting the definition? How does it work? And what is the general principal behind making one?

• Is there anything like deal() for normal MATLAB arrays?

  - by jjkparker

  When dealing with cell arrays, I can use the deal() function to assign cells to output variables, such as: [a, b, c] = deal(myCell{:}); or just: [a, b, c] = myCell{:}; I would like to do the same thing for a simple array, such as: myArray = [1, 2, 3]; [a, b, c] = deal(myArray(:)); But this doesn't work. What's the alternative?

• I need to know inside of "while(fscanf != EOF){blah}" if the next fscanf is going to return EOF-- be

  - by Rancur3p1c

  I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered something like this before and has a cleaner solution.

• With ARC why use @properties anymore?

  - by trapper

  In non-ARC code retained properties handily take care of memory management for you using the self.property = syntax, so we were taught to use them for practically everything. But now with ARC this memory management is no longer an issue, so does the reason for using properties evaporate? is there still any good reason (obviously other than providing public access to instance variables) to use properties anymore?

• What are good or interesting Assembler-like languages, but at a higher level?

  - by CodexArcanum

  I've been looking at L.in.oleum and am intrigued by it's mix of higher-level constructs (loops, dynamic variables) with low-level assembler power (registers). Are there other languages like Lino out there, which blend the speed of assembler with productivity enhancing features? EDIT: I realized this kind of sounds like an ad. I'm genuinely interested in other assembler-like languages, Lino is just the only one I happen to know of.
