我的数组中的双重结果( mysql_fetch_array ) [英] double results in my array ( mysql_fetch_array )

问题描述

好的，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>";
} 

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"

and by doing so i get double output ... "1 1 1 1 jordan jordan 9108121544 9108121544 testEmail testEmail testAddress testAddress testCounty testCounty"

下面是print_r的结果

this below is the result of print_r

 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
    )

我在数据库中的信息是 id =>1 ，department_id => 1 ，依此类推...我的问题是为什么我得到双重反馈(我不知道怎么称呼)，0 = id，1 = Department_id，2 = name 等等..

The information i have in the database is id =>1 , department_id => 1 , and so on ... My question is why i get double feedback(i don't know how to call it) , 0 = id , 1 = department_id , 2 = name and so on ..

当我执行 foreach( ... ) 时，我得到的一切都翻了一番.

and when i do foreach( ... ) i get everything doubled.

推荐答案

来自手册:

mysql_fetch_array — 以关联数组、数值数组或两者的形式获取结果行

mysql_fetch_array — Fetch a result row as an associative array, a numeric array, or both

默认情况下，mysql_fetch_array 提供关联索引和数字索引.你不想要这个.你可以用第二个参数来限制它:

By default, mysql_fetch_array gives both associative and numeric indexes. You don't want this. You can limit it with the second parameter:

$query_result_array = mysql_fetch_array($query_result, MYSQL_NUM); // numeric keys only
$query_result_array = mysql_fetch_array($query_result, MYSQL_ASSOC); // associative keys only

你也可以使用mysql_fetch_row来只获取数字键，或者mysql_fetch_assoc 只获取关联键.

You can also use mysql_fetch_row to only get numeric keys, or mysql_fetch_assoc to only get associative keys.

$query_result_array = mysql_fetch_row($query_result); // numeric keys only
$query_result_array = mysql_fetch_assoc($query_result); // associative keys only
