The Closure class

The Closure class

(PHP 5 >= 5.3.0)

简介

Class used to represent anonymousfunctions. 

Anonymous functions, implemented in PHP 5.3, yield objects of this type.This fact used to be considered an implementation detail, but it can nowbe relied upon. Starting with PHP 5.4, this class has methods that allowfurther control of the anonymous function after it has been created. 

Besides the methods listed here, this class also has an __invoke method. This is for consistency with otherclasses that implement callingmagic, as this method is not used for calling the function.
