Answer 1

As simple as it is..

SELECT id,option_key,option_value FROM options

or

SELECT * FROM options

You can do like this Using PDO

    $dbh = new PDO("mysql:dbname=pages;host=localhost", "username", "password");
    $sth = $dbh->prepare('SELECT id,option_key,option_value FROM options');
    $sth->execute();

Answer 2

尝试这个

SELECT * FROM TABLENAME ;

Answer 3

SELECT * FROM options` then, in the PHP:

while ($row=MySQLi_fetch_assoc($result))
{
    echo "<option value=\"".htmlspecialchars($row['option_value'])."\">".
    htmlspecialchars($row['option_key'])."</option>";
}
