Uploading multiple files - Notice: Array to string conversion in

include "host.php";
$name = $_POST['name'];
$size = $_FILES["files"]["size"];
$type = $_FILES["files"]["type"];
$error = $_FILES["files"]["error"];
$lista = $_FILES["files"]["name"];
foreach ($lista as $nome_immagine) {
   $file = basename($nome_immagine);
   $uploadfile = "photo1/$file";
   echo $uploadfile;
   $temp = $_FILES["files"]["tmp_name"];
    mysql_query("INSERT INTO prova (gruppo, img) VALUES ('$name', '$file')") or die(mysql_error());
    move_uploaded_file($temp, $uploadfile);
    error_reporting(E_ALL); 
}
### Chiudiamo il Database ###
mysql_close($conn_host);

这是上传多个文件。给我这个错误：

注意：数组到字符串的转换...

这里： move_uploaded_file（$temp， $uploadfile）;

为什么？

由于您要上传多个文件，因此$_FILES["files"]["tmp_name"]是一个数组，因此您需要像所有其他$_FILES元素一样对其进行索引。

foreach ($lista as $index => $nome_immagine) {
    $file = basename($nome_immagine);
    $uploadfile = "photo1/$file";
    echo $uploadfile;
    $temp = $_FILES["files"]["tmp_name"][$index];
    mysql_query("INSERT INTO prova (gruppo, img) VALUES ('$name', '$file')") or die(mysql_error());
    move_uploaded_file($temp, $uploadfile);
    error_reporting(E_ALL); 
}
