As we said before, the method that declares the method name of "__" in the class (provided to us by PHP) is the method that executes automatically at a certain time under different circumstances, and the "__tostring ()" method is also automatically called, which is called automatically when the object reference is directly exported. We said before that the object reference is a pointer, for example: "$p =new person ()", $p is a reference, we can not use the Echo Direct output $p, this will outpu

The article at the beginning of the list of so many contact, it will inevitably make you feel a bit of ad's meaning, but can not be questioned, there is really so little performance to ^_^, although sometimes too meticulous will be said mother, but fortunately this meticulous for programming, or pretty good!

I always wanted to learn Java because of curiosity and free. But because it is not used at work, and it is too high in hardware configuration, it is only occasionally used to learn. I have found tutorials and articles on the Internet, but I have not learned anything. I also bought more than 700 pages of Java j2se 5 edition reference book, because it is too thick to read. Finally, I bought a "Java programming practice

Programming | Tutorial 2.5 event handler function said the usual events, in terms of two different ways of dealing with events. The event-handling code described earlier is added like this: First, select the object that will capture the event (the movie clip instance or button), and then open the script panel and write the "on event name" code. For example, if we want a movie clip instance to capture the
