Assigning a string to a while loop list

PHP
1

please i am trying to assign a while loop result to a string so as to be able to send the list in an email, but cant get it, i tried to echo the string $list but the result came back as with only the last row inserted


    $pplresult = mysql_query("SELECT * FROM repplac");
    while($row = mysql_fetch_assoc($pplresult)){
    $list = $row['Sname'] .$row['Pname'] .$row['Psize'] .$row['Pcolour'] .$row['Pquantity'] .$row['Price'] ;}
    echo "$list";
    die();
    // sending email
    $to = $email;
    $subject = "YOUR ORDER LIST FROM FINDER";
    $headers = "From: donotreply@finder.co.uk";
    $body = "$list";
    //send emil
    mail($to,$subject,$body,$headers);
    $transfer = mysql_query("INSERT INTO wishlist SELECT * FROM repplac")or die(mysql_error());
    $deletetable = mysql_query("DELETE FROM repplac")or die(mysql_error());
    redirect_to('youraccount.php');

// init the string (or use and empty string "")
$list = "My start of string: ";  

   while($row = mysql_fetch_assoc($pplresult)){ 

// concat string with .= (no space between them!)
    $list .= $row['Sname'] . ', ' .$row['Pname'] .$row['Psize'] .$row['Pcolour'] .$row['Pquantity'] .$row['Price'] ;

} 

// does not need quotes to echo it out
    echo $list; 
    die();

Also shows concat . ', ’ . to add a comma, space.
