Strange symbols in email

[The Little Guy]

I am reading email that is sent to my server, when I get a message from a Gmail account, gmail adds things like: =A0,=, 3D and other symbols for some reason.

 

This message was send from Gmail

Maybe it is my email server, or maybe it is Gmail...

 

Here is the code I use to get the full email:

$fd = fopen("php://stdin", "r");
$msg = "";
while (!feof($fd)){
  $msg .= fread($fd, 8192);
}
echo $msg;

 

latter on, I save $msg to a db table. Why are those symbols there? They aren't there in the original email...
