$out_hos_re_26 = sql_query("select * from g4_write_membership where (wr_1 between '00000000' and '$to_date') AND wr_26 = $to_date");
$out_hos_re_30 = sql_query("select * from g4_write_membership where (wr_1 between '00000000' and '$to_date') AND wr_30 = $to_date");
$out_hos_re_33 = sql_query("select * from g4_write_membership where (wr_1 between '00000000' and '$to_date') AND wr_33 = $to_date");


3개의 쿼리문으로 구한 데이터를 하나로 합치려고 아래 처럼 했는데 안되네요..

$result = array($out_hos_re_26 + $out_hos_re_30 + $out_hos_re_33);

for ($i=0; $row=sql_fetch_array($result); $i++) {

echo $row[wr_subject];
}


array 말고 join , array_merge 사용해도 안되네요...

방법이 있을까요???
