Php can you change a static variable

Hopefully it will be fixed can't see a reason why it wouldn't. A static variable will be inherited unless not defined again. However this 'unless' part is wrong, it rsults in a compiler error.

From the docs: Declaring class properties or methods as static makes them accessible without needing an instantiation of the class. Jeff Puckett PatrikAkerstrand PatrikAkerstrand So if I moved the static variable to a class, would I then be able to switch it's value back and forth between the executions of my main script?

Static can be used to declare class variables or within function to declare a variable which persists over function calls, but not over executions of the script. I thought that was the point with static variables, that they DO persist over executions. I'd prefer not to keep it in a separate file or is that the only solution?

But you have to store the current value of the variable somewhere. These variables can be accessed directly outside a function. Static variable : It is the characteristic of PHP to delete the variable , ones it completes its execution and the memory is freed.

A static method or, block belongs to the class and these will be loaded into the memory along with the class. You can invoke static methods without creating an object. But static contexts methods and blocks doesn't have any instance they belong to the class. A static method can be called directly from the class, without having to create an instance of the class. A static method can only access static variables; it cannot access instance variables.

Since the static method refers to the class, the syntax to call or refer to a static method is: class name. A static method is a method that is shared by all instances of a class. And they can be private or public. If they are public then you can call them without the need to instantiate the classes. I mostly used static methods in the helper classes or utils classes. Static properties are used when we'd like to store class-level data, also not bound to an instance.

In general, polymorphism means the ability to have many forms. If we say it in other words, " Polymorphism describes a pattern in Object Oriented Programming in which a class has varying functionality while sharing a common interfaces.

Static variables are used with the class name and the dot operator, since they are associated with a class, not objects of a class. Static methods cannot access or change the values of instance variables , but they can access or change the values of static variables.

Static methods cannot call non- static methods. How can I store a value in a variable permanently? How can I permanently save value in string variable of master page using vb. Layout: fixed fluid.
