我有以下 print_r，它源自“多个（不是错字）文件上传”。

Array
(
[file] => Array
    (
        [name] => Array

                        [1] => 0

            )

        [size] => Array
            (
                [1] => Array
                    (
                        [0] => 2776165
                        [1] => 2380025
                    )

                [2] => Array
                    (

                        [2] => 1770128
                    )

                [3] => Array
                    (
                        [0] => 2776165
                        [1] => 2380025
                    )

            )

    )

)

<?php
if(isset($_FILES['file'])=== true){
$files = $_FILES['file'];
for($x = 0; $x < count($files['name'][$x]); $x++){
    $file_name = $files['name'][$x];
    $tmp_name = $files['tmp_name'][$x];
    move_uploaded_file($tmp_name, 'documents/'.$file_name);
}}?>

我想我需要嵌入另一个 for 循环来访问实际名称和 tmp 数组... name1、name2、name3。我希望能够访问每个子数组，以便可以相应地移动它们

我认为您处理此问题的最佳方法是重构生成数组的代码，以便将相关字段放在一起。也许是这样的结构：

Array
(
[file] => Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [name] => IMG_8502 f 5 .jpg
                        [type] => image/jpeg
                    )
...

然后你可以遍历文件：

foreach($files as $upload) {
    foreach($upload as $file) {
        move_uploaded_file($file['tmp_name'], 'documents/'.$file['name']);
    }
}

我用这样的东西，试试看；

function assoc($files) {
    // single image
    if (!is_array($files['name'])) {
        return $files;
    }

    // multiple images
    $assoc = array();
    foreach ($files as $key => $array) {
        foreach ($array as $i => $value) {
            $assoc[$i][$key] = $value;
        }
    }

    return $assoc;
}

echo '<form method="post" action="" enctype="multipart/form-data">
        File 1: <input type="file" name="file[]">
        File 2: <input type="file" name="file[]">
        <input type="submit" name="submit" value="Send">
      </form>';

// and using
if (isset($_FILES['file'])) {
    $files = assoc($_FILES['file']);
    foreach ($files as $i => $file) {
        $move =@ move_uploaded_file($file['tmp_name'], 'documents/'. $file['name']);
        if ($move === true) {
            // remove moved file from array stack
            unset($files[$i]);
        }
    }
}

// display not moved files
print_r($files);

// flash errors
if (!empty($files)) {
    foreach ($files as $file) {
        print $file['name'] ." not uploaded!\n";
    }
}

出局；

// print_r($_FILES);
// print_r(assoc($_FILES['file']));
