PHP file upload path

Assume that the uploaded file name value is upload

<input type="file" name="upload" />

The server processing code is as follows:

if(isset($_FILES['upload']) && !$_FILES['upload']['error']) {                   // 文件存在且不报错
    $fileName = $_FILES['upload']['name'];                                      // 获取文件
    $fileExtension = pathinfo($fileName);                                       // 获取文件路径信息
    $fileExtension = $fileExtension['extension'];                               // 获取文件后缀
    $time = time();                                                             // 根据时间戳区分
    $destinationPath = "./../upload/";                                          // 目标文件夹
    $newFileName = $destinationPath.$time.".".$fileExtension;                   // 完整的url
    if(move_uploaded_file($_FILES['upload']['tmp_name'], $newFileName)) {       // 移动文件到目标路径
        echo("文件移动成功");
    } else {
        die("文件路径出错");
