Что-то типа этого:
$sql_c = "select count(topic_id) from topics";
switch ($section){
case "1": $sql = "$sql_c where section='1'";
$section_name = strtoupper($sec_1);
break;
case "2": $sql = "$sql_c where section='2'";
$section_name = strtoupper($sec_2);
break;
case "3": $sql = "$sql_c where section='3'";
$section_name = strtoupper($sec_3);
break;
case "all":$sql = $sql_c; $section_name = strtoupper($sec_123);
break;
}
$result = mysql_query($sql);
