think PHP makes things complicated.) the default self: staticFun () calls the static function of the subclass, what if we want to call the static variables of the parent class at this time? Here, PHP provides additional parents to call static members of the base class. For
PHP static member variables and non-static member variables, PHP static
data members can be divided into static variables, non-static variables, two kinds .

The static and static variables of the PHP class are introduced. if you are a friend of php, you can see that in php, the methods/variables of the static class have two methods:
1. create an object $ object = new Class () and the
."method is called,"."Parameters:"; Var_dump ($arguments); }Else{Trigger_error ("Illegal call! ", e_user_warning); } }/* When a static method call is not present for an object of the class, this method is called automatically 5.3.0 new __callstatic () Magic method. A warning is generated when visibility is not set to public or not declared as static */ PublicStatic function__callstatic($name , $arguments){
In PHP, there are two ways to access a class's methods/variables:
1. Create Object $object = new Class (), and then use "->" to invoke: $object->attribute/function, provided that the variable/method is accessible.
2. Direct call to class method/variable: class::attribute/function, either static/Non-static. But there are prerequisites:
A. If it is a variable, you
In php, there are two methods for methods/variables of the callback class:1. Create an object $ object = new Class () and then use "->" to call: $ object-> attribute/function, provided that the variable/method is accessible.2. directly call the class method/variable: class: attribute/function, either static or non-static.

The results of the operation are as follows:

Best of all, according to the above example, it is easy to think that the subclass access parent class can use the parent keyword, then how does the parent class access the static method of the subclass? Here's another way to use static, where if you change

Static keyword memory analysis and static keyword Analysis
Generally, Java divides memory into stack memory, heap memory, and method areas. stack memory is used to store some basic types of variables and arrays (arrays are also a reference type) and object reference variables, and the heap memory is mainly used to plac
redirection, leading to the inability to obtain parameters passed by post (get. The above analysis is actually unable to find the relevant file, then when the server cannot find the relevant file, we specify a file for it, it will not be OK, it does not need to jump, at this time, POST and so on will not be lost. The apache configuration is as follows:
RewriteEngine OnRewriteCond % {REQUEST_FILENAME }! -FRewriteCond % {REQUEST_FILENAME }! -DRewriteRu
