"; // Your other operations .}

Explode function. Use google
------ Solution --------------------
Why are people always asking these questions?
I think this is an attitude issue.
At least the manual is usually used to double the character string.
Even if you do not know the built-in functions of php
You can also write an algorithm yourself.
However, it is highly efficient to understand basic common functions.
Ignore me if I have any questions.

Although it is a bit radical, it makes sense. it is recommended that you check the manual more.
