why this code save file data in wrong structure? php

I have this code:

<?php
$a = file_get_contents('a.txt');
$a .= "test2\r\n";
file_put_contents('a.txt', $a);
var_dump( file_get_contents('a.txt')) ;
?>

and this is content of a.txt before executing the code:

test1

when run it this result showed to me in browser:

string 'test1
test2
' (length=14)

but when I open the a.txt by notepad I saw this content:

test1
test2
test2

and when I execute code again it saw this result in browser:

string 'test1
test2
test2
test2
' (length=28)

but content of a.txt after execute was this in notepad:

test1
test2
test2
test2
test2

but why?

I asked a similar question at why this code adds two point every time that executes but no one answered a good answer to me :((

You are always appending test2\r\n to what's already in the file.
