有人可以帮助我吗？我正在尝试更新MYSQL DB中的文件并将上载的文件移动到文件夹“ upload / documents /”，但是我似乎无法在docUpload中获取文件。我不断收到此通知：C：中的未定义索引：“ docfile”。谁能帮帮我吗。这是我的$ _files的var_dump：
Array
(
[name] => Array
(
[1001] => Array
(
[101] => Array
(
['docUpload'] => test.txt
)
[1010] => Array
(
['docUpload'] => test 2.txt
)
)
[901] => Array
(
[701] => Array
(
['docUpload'] => test 3.txt
)
[901] => Array
(
['docUpload'] =>
)
)
)
[type] => Array
(
[1001] => Array
(
[101] => Array
(
['docUpload'] => text/plain
)
[1010] => Array

)
)
[901] => Array

)
[901] => Array
(
[701] => Array
(

[901] => Array
(
['docUpload'] => 4
)
)
)
[size] => Array
(
[1001] => Array
(
[101] => Array
(

)
[1010] => Array

)
[901] => Array
(
[701] => Array
(

)
[901] => Array
(
['docUpload'] => 0
)
)
)
)
这是我到目前为止所做的：
$producySelected = $_FILES['docUpload'];
if(!empty($producySelected))
{
$icount = 0;
foreach($producySelected as $key=>$selected)
{
$icompte = 0;
foreach($selected as $keyz=>$value)
{
echo "<pre>";
echo($key);
echo "<br>";
echo($keyz);
echo "<br>";
echo ($value["'docUpload'"]); ??
echo "<br>";
echo "</pre>";
$icompte++;
}
$icount++;
}
}
