게시판 복사 코드를 작성하는데

$g5['board_table'] = "g5_write_aaa"; $aaa_columns = sql_field_names($g5['board_table']);

$g5['board_table'] = "g5_write_bbb"; $bbb_columns = sql_field_names($g5['board_table']);

를 print_r 해보니 아래처럼 잘나옵니다.

aaa

 wr_1 [73] => wr_2 [74] => wr_3 [75] => wr_4 [76] => wr_5 [77] => wr_6 [78] => wr_7 [79] => wr_8 [80] => wr_9 [81] => wr_10 [82] => wr_11 [83] => wr_12 [84] => wr_13 [85] => wr_14 [86] => wr_15 [87] => wr_16 [88] => wr_17 [89] => wr_18 [90] => wr_19 [91] => wr_20 [92] => wr_21 [93] => wr_22 [94] => wr_23 [95] => wr_24 [96] => wr_25 [97]  )

bbb

 wr_1 [73] => wr_2 [74] => wr_3 [75] => wr_4 [76] => wr_5 [77] => wr_6 [78] => wr_7 [79] => wr_8 [80] => wr_9 [81] => wr_10 [82] => wr_11 [83] => wr_12 [84] => wr_13 [85] => wr_14 [86] => wr_15 [87] => wr_16 [88] => wr_17 [89] => wr_18 [90] => wr_19 [91] => wr_20 [92] => wr_21 [93] => wr_22 [94] => wr_23 [95] => wr_24 [96] => wr_25 [97] => wr_26 [98] => wr_27 [99] => wr_28 [100] => wr_29 [101] => wr_30 [102] => wr_31 [103] => wr_32 [104] => wr_33 [105] => wr_34 [106] => wr_35 [107] => wr_36 [108] => wr_37 [109] => wr_38 [110] => wr_39 [111] => wr_40 [112] => wr_41 [113] => wr_42 [114] => wr_43 [115] => wr_44 [116] => wr_45 )

이제 

            $sql = " insert into $move_write_table                          set 

                              $bbb_columns = '$aaa_columns', wr_num = '$next_wr_num' ";

print_r($sql);

            sql_query($sql);             $insert_id = sql_insert_id();

이렇게 하니

insert into g5_write_bbb set Array = 'Array', wr_num = '-36498'

이렇게만 나오고

  $bbb_columns = '$aaa_columns', 이부분이 안나오는데

뭐가 잘못된걸까요?
