The functions are all very similar: mysql_fetch_array(), mysql_fetch_assoc(), mysql_fetch_object() I have recently started using mysql_fetch_object as I am doing alot more OOP with PHP. But what are peoples opinions on which one is best to use and why, and maybe which scenario they are best to be used in. Thanks for your thoughts! ...

I'm writing some JavaScript with three classes, one for Roofs, one for Garages, and one for Houses. The house class takes two arguments to its constructor, a Roof and a Garage. When I run this code I get: can not construct object [Break on this error] throw new Error('can not construct object');\n in Firebug even though the objects are...
Hi, just for my understanding. Does my example code below actually changes the the color of my Car Object in the IntHashtable or does the first line creates another instance of the car object, which contains color = red after the second line? thanks, Henrik Car myCar = (Car)myIntHashTable.get(index); myCar.setColor = red; Edit: Is...
Example: class UserStorage { public function addUser(User $user) { //saves to db } } class User { public function setName($name); } What if I add a user to the user storage and later change that user object? In this case you might argue that user objects only should be stored on __destruct. But sometimes this isn't an option ...
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members. Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function? Thanks! ...
When dealing with large collections, which of the following approaches is better? Class SimpleObject with only fields/properties and class SimpleObjectController that contains all the method implementations required by SimpleObject. At runtime, I build a collection of SimpleObjects, instantiate one SimpleObjectController and call it's m...
Hi, I'm still new to programming so excuse me if this is silly. I'm programming a simple game and require multiple timers to send different messages at different intervals, so when creating the game, the following is called: [self gameTimerValidate]; [self scoreTimerValidate]; - (void) gameTimerValidate { gameTimer = [NSTimer scheduled...
Consider the following code: class myarray { int i; public: myarray(int a) : i(a){ } } How can you create an array of objects of myarray on stack and how can you create an array of objects on heap??? ...
I'm using a compiler that has a slightly older version of PHP than my dev machine (5.1.3 vs. 5.2.6 IIRC). That version doesn't do the auto-conversion, which can result in some sneaky bugs in the compiled version. I'd rather not downgrade my dev box, but if I can somehow turn that off, that might be helpful in finding those earlier. ...

Working with my ongoing TFrames-based component set project, I'm coming across various instances where I am wanting to replace one of the TFrame's components (usually non-visual) at runtime with one that is generated dynamically at runtime. I think I've probably found the answer to my immediate problem here, but in my own digging arou...
Objective C on iPhone: I am attempting to declare the following object at class level so that i do not have to re-connect this socket every time I write something to it. (Writing things multiple times a second) whenever i am writing a steady stream of live data, about every 2 seconds it freezes. I don't know why, but it does. Code: Soc...
Hey there, I am using the following method to basically create a JSON string. var saveData = {}; saveData.a = 2; saveData.c = 1; However the .a and .c don't cut it for what I need to do, I need to replace these with strings. So something like.. var name = 'wibble'; saveData.name = 2; This would get accessed with saveData.wibble ...
I'm trying to teach myself C++, and one of the traditional "new language" exercises I've always used is to implement some data structure, like a binary tree or a linked list. In Java, this was relatively simple: I could define some class Node that maintained an instance variable Object data, so that someone could store any kind of object...
In the following code, it seems I only get the 'otherboxclick' call for the last box added (b1). If I change the order the boxes are added, it's always just the last one that works. How can I get it to work for all the boxes? <html> <head> </head> <body> <script type="text/javascript"> function otherboxclick(e){ alert("other...
I have a dynamic linked library written in C# 3.0. This library has a small set of public classes that I want to make XML representations for. The idea is to allow "saving/loading" of objects from disc using XML as the representation. I would also like to allow users of the class library to pass these XML representations to certain funct...
What are the differences between these two codes in JavaScript? var obj = new Object(); obj.X = 10; obj.Y = 20; And, var obj = {X:10, Y:20}; ...
Hi, I have a validation class which I would like to use to check all values in my application are within allowed constraints. I am passing an object to a static function within the validation class, from another class (in this case User) function validate() { $errors = Validation::validate($this); } In the validation class, I cre...
