This article will explain in detail how to use the php increment and decrement operator. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Php increment and decrement operator + +--

Description:

Add one or minus one by yourself.

+--

Note:

If you give a variable +-- and no longer assign a value, there is little difference between pre-addition and post-addition.

When another variable is assigned a value after addition or subtraction, there is a difference between pre-addition and post-addition.

Summary:

Before: add and subtract the operation before assigning

After: assign the value and then add and subtract the operation

/ / increasing and decreasing / / there is no difference between for.
