Article 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 , mentioned the cloning method. 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

Article Introduction：We have already known before that when calling an object using pass-by-reference, 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 use the current object according to the current object. To clone an identical object, the cloned copy is completely independent of the original two objects and does not interfere with each other. Let’s take a simple example to see how to use cloning:
