Question

我在网站上有一个上传表单，可以将多个文件上传到服务器，还会向我发送一封电子邮件。它是用php编写的，主文件部分如下：

if (isset($_FILES) && (bool) $_FILES) {
    $files = array();
    $ext_error = "";
    // Define allowed extensions

    // blahblahblah checking

    // Store attached files in uploads folder
    $server_file = dirname(__FILE__) . "/uploads/" . $path_part['basename'];
    move_uploaded_file($temp_name, $server_file);
    array_push($files, $server_file);

如今，人们通过手机上传图片，并且通常它们都被命名为相同的文件名：image.jpg（或类似的东西） - 所以它们会被覆盖。

我想在每个多个文件（如1,2,3 ......）上附加一个计数器，以便上传并以唯一名称发送，即使客户端将它们作为同名发送。

类似的东西：

if (isset($_FILES) && (bool) $_FILES) {
    $files = array();
    $ext_error = "";
    // Define allowed extensions

// counter= counter++;
// newFilename=oldFileName+String(counter);

// doRestStuffNewFileName();

// blahblahblah checking

// Store attached files in uploads folder
$server_file = dirname(__FILE__) . "/uploads/" . $path_part['basename'];`
`move_uploaded_file($temp_name, $server_file);`
array_push($files, $server_file);`

如何在php中修改它？

好的新评论：

我想：

for int i=0;i<files[attached];i++;
fileName=files[i]
newFileName=filename+String(Integer(i));
uploadWithNewFileName();
writeToServerWithNewFileName();

这是php当前代码：

if (isset($_FILES) && (bool) $_FILES) {
$files = array();
$ext_error = "";
foreach ($_FILES as $name => $file) {
    if (!$file['name'] == "") {
        $file_name = $file['name'];
        $size += $file['size'];
        $temp_name = $file['tmp_name'];
        $path_part = pathinfo($file_name);
        $ext = $path_part['extension'];

        // Store attached files in uploads folder
        $server_file = dirname(__FILE__) . "/uploads/" . $path_part['basename'];
        move_uploaded_file($temp_name, $server_file);
        array_push($files, $server_file);
    }
}

为什么这不起作用：

if (isset($_FILES) && (bool) $_FILES) {
$files = array();
$ext_error = "";
counter =0; //My code

foreach ($_FILES as $name => $file) {
   counter++; //My code
    if (!$file['name'] == "") {
        $file_name = $file['name'];
        $size += $file['size'];
        $temp_name = $file['tmp_name'];
        $path_part = pathinfo($file_name) + counter; //My code
        $ext = $path_part['extension'];

        // Store attached files in uploads folder
        $server_file = dirname(__FILE__) . "/uploads/" . $path_part['basename'];
        move_uploaded_file($temp_name, $server_file);
        array_push($files, $server_file);
    }
}

如何重命名上传的文件以使其独一无二？
