How to import multiple variables from the database into one variable with transfers?

Question

PHP

There is a db in which there are several textual/numerical values. Text values ​​are both single-line and multi-line. For example, I need to import these variables into one variable ($message) in order to insert it into the database later. $message variable example:
Hello, your order has been processed and is ready to ship.
You bought an elephant for $var1.
The weight of the elephant is $var2
. $var3. Thank you
for your purchase!
How to make such a variable, or is it necessary somehow differently?

What for? What is the point of shifting from one pocket to another?
All this data you already have in the database.
