php - mysql多维数据

Question

我需要用这样的东西从我的数据库中输出多行选择。它正在输出第二行但不是第一行，并返回警告“警告：非法字符串偏移量'char_name'”

$i = 0;
while($array = @mysql_fetch_assoc($query)){
    $row[$i] = $array;
    $char = $row[$i]['char_id'];
    $$char['char_name'] = $row[$i]['char_name'];  /warning is on this line

    echo $char . " " . $$char['char_name'];$i++;
}

Answer 1

你能重建代码吗：

$i = 0;
while($array = @mysql_fetch_assoc($query)){
    $row[$i] = $array;
    $char = $row[$i]['char_id'];
    $char_name = $row[$i]['char_name']; 

    echo $char . " " . $char_name;
    $i++;
}

Answer 2

将此更改为

$$char['char_name'] = $row[$i]['char_name'];  /warning is on this line
echo $char . " " . $$char['char_name'];
$i++;

这个

$char['char_name'] = $row[$i]['char_name'];  /warning is on this line
echo $char . " " . $char['char_name'];
$i++;
