How to simulate the curd operation of single linked list in PHP

In this issue, the editor will bring you about how to simulate the curd operation of a single linked list in PHP. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Single linked list official definition: a single linked list is a linked data structure in which a set of storage units with arbitrary addresses are used to store data elements in a linear list. The data in the linked list is represented by nodes, the composition of each node: element (the image of the data element) + pointer (indicating the storage location of the subsequent element), the element is the storage unit for storing data, and the pointer is the address data connected to each node. (it's not what I said, it's official, but I guess you want to swear after reading it.)

The following example diagram is a single linked list. The tail pointer is a null, and the middle part is connected by a pointer.

Next we will use php to simulate the single linked list: code->

Parameter description: the following method head represents a linked list, hero represents the object of a hero, and num represents the number of the hero. The following code will not be repeated.

The above code is that we simply simulate how to use PHP language to implement a single linked list, of course, the above method is very stupid, let's modify it a little bit.

Here is the test code for the above code:
