How to fix, assignments must be the first block of code on a line?

Question

I'm developing WordPress plugin and stuck with code sniffer warnings. How do I fix the below warning message?

[Squiz.PHP.DisallowMultipleAssignments.Found] Assignments must be the first block of code on a line

The above error/ warning is highlighting for the below code.

$testimonial_gravatar_image = $out = $before = $after = '';

How do I define those empty variables? If I skip or remove then the error displays undefined variable etc.

$testimonial_gravatar_image is inside the while loop and $out for generating output.

The sniffer rule is named "DisallowMultipleAssignments". It doesn't accept multiple chained assignments. Initialize each variable with the empty string in a separate statement. — axiac, Oct 05 '17 at 06:34
Isn't there any other logics to do or avoid or suppress the warning :) — Maqk, Oct 05 '17 at 06:47
