PHP 电子邮件表单 - 为每个输入数组分配一个变量

我正在根据表单的输入整理PHP邮件。

在实际表单上，我有这个文件输入：

<input type="file" name="fileToUpload[]">

对于电子邮件，我希望有一个标签，例如"附件"，然后将所有上传的文件列为 url。示例：如果上传了 file1.jpg，则电子邮件中的输出将 www.myurl.co.uk/file1.jpg

请注意，我试图通过为输入 1 等设置 $target_file1 来做到这一点的糟糕方式。除了糟糕的代码之外，问题是，例如，如果输入 2 没有文件，电子邮件输出仍将显示 url 的第一部分"http://www.myurl.co.uk/uploads/"

获取多个文件输入并将它们全部列为电子邮件中的 url 的最佳方法是什么？

<?php
for($i=0; $i<count($_FILES['fileToUpload']['name']); $i++) {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"][$i]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"][$i], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"][$i]). " has been uploaded.";
    } else {
