Insert Array

programming
1

I am try to insert an array which i have done but the data inserts with junk:

Currently adds:
a:2:{i:0;s:9:“Stratergy”;i:1;s:6:“Design”;}

But it should look like:
“Stratergy”, “Design”


if(is_array($_POST['discipline'])) {
$posttypeserialized = serialize($_POST['discipline']);
}

 $result=MYSQL_QUERY("INSERT INTO portfolio (portId,discipline)".
  "VALUES ('NULL', '".mysql_escape_string($posttypeserialized)."')");
