Are you getting any errors?

You need to add else to the end of your if statement.
So do something like:

if ($by=="all"){
    $sql="SELECT * FROM request WHERE status='$stts1' OR status='$stts2' OR status='$stts3' OR status='$stts4'";
}else if ($by=="my"){
    $sql="SELECT * FROM request WHERE status='$stts1' OR status='$stts2' OR status='$stts3' OR status='$stts4' AND curPIC='$pic'";
}else{
    $sql="SELECT * FROM request WHERE status='$stts1' OR status='$stts2' OR status='$stts3' OR status='$stts4'";
}
