PHPを使ってMySQLのデータベース内のテーブルすべてをUNION式に変換しながらループで取り出す（原始的な方法）

結論

MySQLの文法でwhileする方法がわからなかった。代替案を実行した。

以下のようなものが出力される。

SELECT title, rank, name FROM $tb_name_list[0] UNION 
SELECT title, rank, name FROM $tb_name_list[1] UNION 
SELECT title, rank, name FROM $tb_name_list[2] UNION

SELECT title, rank, name FROM $tb_name_list[62] UNION 

このSQL文を、PHPコード内にヒアドキュメントとしてコピペする。
UNION式は、最後の行だけは「UNION」の記述が不要なので、削除しておく。 とりあえず応急処置として。
