本文介绍了多维在PHP中的循环的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下的print_r，它是由多个多个（不是笔误）文件的上传。
I have the following print_r, which is derived from "multiple multiple(not typo) file uploads".
Array
(
[file] => Array
(
[name] => Array
(
[1] => Array
(
[0] => IMG_8502 f 5 .jpg
[1] => IMG_8507 f 5 .jpg
)
[2] => Array
(
[0] => IMG_8508 f 5 .jpg
[1] => IMG_8529 f 5 .jpg
[2] => IMG_8612 fff 5 .jpg
)
[3] => Array
(
[0] => IMG_8502 f 5 .jpg
[1] => IMG_8507 f 5 .jpg
)
)
[type] => Array
(
[1] => Array
(
[0] => image/jpeg
[1] => image/jpeg
)
[2] => Array
(
[0] => image/jpeg
[1] => image/jpeg
[2] => image/jpeg
)
[3] => Array
(
[0] => image/jpeg
[1] => image/jpeg
)
)
[tmp_name] => Array
(
[1] => Array
(
[0] => C:\wamp\tmp\php1CC.tmp
[1] => C:\wamp\tmp\php1FC.tmp
)
[2] => Array
(
[0] => C:\wamp\tmp\php23B.tmp
[1] => C:\wamp\tmp\php26B.tmp
[2] => C:\wamp\tmp\php2AB.tmp
)
[3] => Array
(
[0] => C:\wamp\tmp\php2CB.tmp
[1] => C:\wamp\tmp\php30A.tmp
)
)
[error] => Array
(
[1] => Array
(
[0] => 0
[1] => 0
)
[2] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
[3] => Array
(
[0] => 0
[1] => 0
)
)
[size] => Array
(
[1] => Array
(
[0] => 2776165
[1] => 2380025
)
[2] => Array
(
[0] => 2456713
[1] => 2585779
[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循环来访问实际的名称和TMP阵列... 1，名称2，NAME3。我希望能够访问每个子阵列，这样我可以将它们相应地移动
I think I need to embed another for loop to access the actual name and tmp arrays... name1, name2, name3. I would like to be able to access each sub array so that I can move them accordingly
推荐答案
我用这样的事情，尝试一下;
I use something like this, try it;
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 $file['name'] ." not uploaded!\n";
}
}
前前后后;
// print_r($_FILES);
// print_r(assoc($_FILES['file']));
Array
