What is the difference between $varName = "$var \n"; from that with a period: $varName. = "$var \n"? quite confusing.

= is for attributing a value .= is for concatenating
$var = "a"; $var = "b"; // $var will be "b";
$var = "a"; $var .= "b"; // $var will be "ab";

The . operator in PHP means concatenation.
You can use operators with the assignment operator (=) to accomplish both affects.
So these are the same:
$varname .= "stuff";
$varname = $varname . "stuff";

The first one is assigning a value to another variable.
The second one is used to concatenate strings. consider a scenario where you need to concatenate strings within a loop. This one is the best way to do so.
foreach(iteration)
{
$some_variable .= $some_other_variable .",";
}
output is like this : val1,val2,val3 etc..
