    echo $Fetch['addr'].',';

it is displaying

address,city,postalcode

if i remove postalcode it displayes

address,city,

but i don’t need , at the end when any of the value is not provided

Answer 1

Store the output in a variable do not echo directly with if as you are doing and then use below function and finally print them after applying rtrim on the $str.

string should be stored in $str with all the if‘s

if ($Fetch['addr']!=''){
    $str.=$Fetch['addr'].',';

This will remove last comma

echo $clean = rtrim($str,',');
