10 recommended articles about cloning objects

This section explains the cloning of content objects, the traversal of objects, the serialization and deserialization of objects, the use of built-in standard classes, the use of traits, the related functions of classes and objects, PHP reflection mechanism, Preface to PHP's object-oriented knowledge point, which is an important knowledge point. , its ideas run through the entire process of our development. There are some knowledge points in object-oriented that we need to understand, such as the characteristics of object cloning and object traversal, object serialization and deserialization. If you want to write a PHP framework, then your reflection on PHP is also To be mastered. Cloning of objects: When we create an object, a space will be allocated in the memory, and the object name points to this space. We talked about the assignment of objects earlier. When one object modifies the data inside, the data of the other object will also Follow the changes, because assignment is equivalent to assigning a copy of the object identifier, but cloning is not like this.

2. JavaScript Deep Clone Object

Introduction: Today’s question I saw deep cloning objects and asked to program on the prototype chain, so I decided to review this knowledge point on a whim. Cloning objects may seem like a fancy term, but it’s actually nothing. It’s just copying an object that looks exactly the same. Maybe some beginners have it. My partner is thinking, isn't that simple? so easyvar obj1 = {name: 'payen'};var obj2 = obj1; This is not a cloned object. obj1 and obj2 are basically the same object. They point to the same memory address. Space, got it

9. php object-oriented clone object

Introduction: In the previous PHP object-oriented object and Reference, we tried to copy the object in the way of "$b=$a" to pass the value (content) of the object, but the result was to pass the address of the object. At the end, in order to solve the problem of copying the object, the cloning method was mentioned. Next, let’s talk about PHP object-oriented cloning objects. We already know from the previous point that when calling an object using a pass-by-reference method, the actual call is the same object. Sometimes it is necessary to create a copy of the object. When changing the original object, we do not want to affect the copy. In PHP, we can do this according to the current Object to clone an identical one
