上傳小程式分享
今天興致來的時候，寫了一個上傳檔案的程式
功能說明：
1. 一次可上傳 多個檔案，預設為10個，數目可自己調
2. 每個檔案都丟到不同的目錄，防止檔名相同時被 over write
目前以 time stamp 命名
3. 解決中文檔名許蓋功問題
code如下，有興趣可以參考看看，如果有Bug也請提出...
<?php
set_time_limit (0);
ini_set('memory_limit', '-1');
$upload_dir = 'E:/upload'; // 上傳目錄，請自行設定
if (!is_dir($upload_dir)) mkdir($upload_dir);
$max_upload_file = 10; // 上傳檔案數目
$msg = '';
if (isset($_POST['filename']) && is_array($_POST['filename']))
{
foreach ($_POST['filename'] as $num=>$name)
{
if ($name!='' && $_FILES['file']['tmp_name'][$num]!='' && is_file($_FILES['file']['tmp_name'][$num]))
{
$dest_dir = "$upload_dir/" . time();
if (!is_dir($dest_dir))
mkdir($dest_dir);
else
{
$i = 2;
while (1)
{
$new_dest_dir = "$dest_dir.$i";
if (!is_dir($new_dest_dir))
{
mkdir($new_dest_dir);
$dest_dir = $new_dest_dir;
break;
}
$i++;
}
}
$dest = "$dest_dir/$name";
if (move_uploaded_file($_FILES['file']['tmp_name'][$num], $dest))
$msg .= "<font color='red'><b>$name</b></font> 上傳成功\ <br>\n";
}
}
}
?>
