Why is there an extra percentage sign in the last line of the php script echo a string?

I installed php on ubuntu today and found that the last line of the php file echo a string with an additional percent sign. What is the situation? The Code is as follows {code ...} the execution result is: hello, world! % {Code...}: hello, world! May I ask the first paragraph... I installed php on ubuntu today, and I found that the last line of the php file echo a string with an additional percentage sign. What is the situation? The Code is as follows:

The execution result is: hello, world! %

The execution result is: hello, world!

Why is an extra percentage sign in the first code? Google won't get the answer for a long time, so it's so uncomfortable not to solve it.

Because \ n is not automatically added to you.

On-my-zsh? It may be a shell issue.
