Self-increment and auto-increment operations in PHP that we have pursued in those years (1)

Bytes -------------------------------------------------------------------------------------------

PHP does not have many operators, but not everyone knows how to use them?

Here we will talk about the upgraded version of the PHP operator number: ++, --, haha.

------------------------- @ Chenwei <www. chenwei. ws> ----------------------------

++ Is auto-increment,

-- Auto-subtraction.

Practical application:

$ A = 10; $ a ++ =? // Add the value first, and the final result is 11.

$ A = 10; ++ $ a =? // Add and reuse first. The final result is 11.

 

$ A = 10;

$ B = $ a ++ $;

Echo $;

Echo $ B; // check the result. I will reply to the answer.
