Repeat an if/elseif/else to completion

I'd like to be able to loop the if/elseif/else statement if it falls onto any of the statement that is not "else".

$names is an array with a couple of names that the user will select.

Right now, the code does work but if the condition falls into any of the elseif's then the loop will stop, from the user's perspective it's almost like nothing has happened.

if($names[0] == $poster) {

    shuffle($names);   


} elseif($names[1] == $entertainer) {

    shuffle($names);         


} elseif($names[2] == $tunar) {

    shuffle($names);        


}  elseif($names[3] == $keeper) {

    shuffle($names);        

}  elseif($names[4] == $feeder) {

    shuffle($names);    

}  elseif($names[5] == $provider) {

    shuffle($names);

} else {
        echo "This week's roles are:";

     while($row = mysqli_fetch_assoc($this_week_result) ) {
                $poster = $row['poster'];
                $entertainer = $row['entertainer'];
                $tunar = $row['tunar'];
                $keeper = $row['keeper'];
                $feeder = $row['feeder'];
                $provider = $row['provider'];
            }

        echo $names[0] . " is the Poster <br>";
        echo $names[1] . " is the Entertainer <br>";
        echo $names[2] . " is the Tunar <br>";
        echo $names[3] . " is the Keeper <br>";
        echo $names[4] . " is the Feeder <br>";
        echo $names[5] . " is the Provider <br>";


        $sql = "INSERT INTO funroles 
        (poster,entertainer,tunar, keeper, feeder, provider, date)
        VALUES
        ('$names[0]','$names[1]','$names[2]','$names[3]','$names[4]','$names[5]','$date')";

        $result = mysqli_query($conn, $sql);

        mysqli_close($conn);
}
