php - 访问关联数组 php pdo 时出现问题

Question

我在工作中遇到问题，我正在尝试使用使用提供的值

$row['make'] 

并通过导入将纯文本数据从我们的数据库中提取出来。现在，当我运行此代码时，我遇到了一个问题，我得到了这个

Notice: Undefined index: FORDX in convert.php on line 203

我不确定为什么会发生这种情况，我猜这与我访问数组的方式有关。

这是数组

当我循环遍历 $row['make'] 时来自数据库的示例数据

FORDX VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO VOLVO GRTDN GRTDN 

这是循环代码

$result = $pdo->prepare("SELECT * FROM csvImport limit 20");


$data = array();
if ($result->execute()) {
    while($row = $result->fetch(PDO::FETCH_ASSOC))
    {
        if($row['status']== "P-Sale Pending")
            $status = "Pend";
        else
            $status = "Live";

        $unit = $row['unit'];//stocknumber
        $make = $makes[$row['make']];
    }
}

Answer 1

我知道这不是一个答案，而是一个调试技巧 - 但注释中的格式是不够的。

试试这个:

if (isset($makes[$row['make']]) {
    $make = $makes[$row['make']];
} else {
    echo "unrecognized make for unit {$unit}: ";
    var_dump($row['make']);
    die();
}

...我打赌其中一行的 make 列中有某种空白字符...
