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