How do I create a PHP static class property at runtime (dynamically)?

被刻印的时光 ゝ 提交于 2019-12-04 02:32:59
I'd like to do something like this: public static function createDynamic(){ $mydynamicvar = 'module'; self::$mydynamicvar = $value; } and be able to access the property from within the class with $value = self::$module; I don't know exactly why you would want to do this, but this works. You have to access the dynamic 'variables' like a function because there is no __getStatic() magic method in PHP yet. class myclass{ static $myvariablearray = array(); public static function createDynamic($variable, $value){ self::$myvariablearray[$variable] = $value; } public static function __callstatic($name

objective c dynamic object creation

问题 Quick question for you. I want to be able to create an instance of an object. The object type is based of a string. In php you can just replace the class name with a string, but I doubt it is that easy in Objective c. NSString * className; id theObject; className = @"TestObject"; theObject = [[className alloc] init]; here is a break down of what it might look like. I want to try and avoid using a giant case style statement. Is it possible to use the selector system for this? any ideas? Cheers

问题 I'm preparing for an exam in Java and one of the questions which was on a previous exam was:"What is the main difference in object creation between Java and C++?" I think I know the basics of object creation like for example how constructors are called and what initialization blocks do in Java and what happens when constructor of one class calls a method of another class which isn't constructed yet and so on, but I can't find anything obvious. The answer is supposed to be one or two sentences

iPhone Dev - NSString Creation

拈花ヽ惹草 提交于 2019-12-02 08:29:15
I'm really confused with NSStrings. Like when should I do NSString *aString = @"Hello"; of should it be: NSString *aString = [[NSString alloc] initWithString:@"Hello"]; But then its different when you're assigning a value to an NSString property isn't it? Can someone clear this up for me? Thanks!! In general you should do the first, but they are mostly functionally the same. You can treat constant NSStrings just like normal NSString string objects, for instance: [@"Hello" length] will return 5. You can assign them to properties, everything just works. The one thing you might notice is that
