我正在尝试将简单的 PHP 上传进度条脚本放在דוגמנות网站上
APC 已经安装在您的服务器上，我已经按照说明调整了我的 php.ini。
apc.rfc1867 = 开启
现在的问题是我从上传过程中得到一个 %NaN 而不是实数。
我知道这个脚本正在其他一些服务器上运行，所以我假设脚本上没有错误，它只是与 php.ini 或 APC 相关的东西。
这是我的 upload.php 文件：
<?php
//get unique id
$up_id = uniqid();
//process the forms and upload the files
if ($_POST) {
//specify folder for file upload
$folder = "tmp/";
//specify redirect URL
$redirect = "upload.php?success";
//upload the file
move_uploaded_file($_FILES["file"]["tmp_name"], "$folder" . $_FILES["file"]["name"]);
//do whatever else needs to be done (insert information into database, etc...)
//redirect user
header('Location: '.$redirect); die;
}
?>
