好吧，我执行这个

$table = get_personel_table(1);
function get_personel_table($id)
    {
        global $connection;
        $query  = "SELECT * ";
        $query .= "FROM employees ";
        $query .= "WHERE id=" . $id . " ";
        $query .= "ORDER BY id ASC";
        $query_result = mysql_query( $query , $connection );
        confirm_query($query_result);
        $query_result_array = mysql_fetch_array($query_result);
        return $query_result_array; // returns associative array!;
    }

我做foreach

foreach($table as $table_var)
{
    echo "<td>" . $table_var . "</td>";
}

然后这样做，我得到了双重输出…“ 1 1 1 1 jordan jordan 9108121544 9108121544 testEmail
testEmail testAddress testAddress testCounty testCounty”

这是print_r的结果

 Array
    (
        [0] => 1
        [id] => 1
        [1] => 1
        [department_id] => 1
        [2] => jordan
        [name] => jordan
        [3] => 9108121544
        [EGN] => 9108121544
        [4] => testEmail
        [email] => testEmail
        [5] => testAddress
        [address] => testAddress
        [6] => testCounty
        [country] => testCounty
    )

我在数据库中拥有的信息是id => 1，department_id => 1，依此类推…我的问题是为什么我会得到双重反馈（我不知道怎么称呼），0 =
id，1 = department_id，2 =名称，依此类推。

当我做foreach（…）时，我得到的一切都会翻倍。
