what is the use of dot(.) e.g. ."phpfile" anyone?

Answer 1

. - (dot) might be used for adding items for example:
$yourName = "John";
echo "My name is ".$yourName;
//prints out "My name is John"

Answer 2

If I understand your problem, It is just a extention of PHP like .php. In java it is .java, in c++ it is .CPP.
else if you are asking about . in echo or a string. It is just use to separate PHP variable with constant string like
echo "Hello Renz ".$id
where $id can be any variable.
else I am wrong with both please explain your problem with bit example.
