How to get the value of variables after executing a script remotely via ssh?

Question

bash

Good afternoon!
Please tell me how to solve the problem.
There is a machine 'A' and 'B'
Machine 'A' a script that ssh to machine 'B' and runs the script.
The script is executed, puts something into text files, copies something. Initializes some variables. And now the question is how can I remotely pull out the value of the variables to my machine 'A'.

A-> ssh [email protected] "cd /to/script  && ./script.sh"

B->cat script.sh 
 a=`ls -l | grep 'info`
 b=`dmesg | grep 'error'`
 c=`date`
do
$a $b $c 
done

How it is possible to pull out after working out of a script value of variables to itself on 'A'?

ssh [email protected] "cd /to/script  && ./script.sh"
echo $a $b $c
