我第一次上传了一个test.txt文件上传成功了,后面又上传一个test1.txt文件且内容不相同,上传成功了但是找不到这个文件,我在本地测试发现这两个文件返回了同一个md5_file()的hash值,最后被你的程序识别成了同一个文件,程序如下
public function renameTempFile()
{
$savedFileHash = $this->generateSavedFileHash($this->uploadPartialFile);

    if ( RedisHandler::hashExists($savedFileHash) ) {
        $this->savedPath = RedisHandler::getFilePathByHash($savedFileHash);
    } else {
        $this->savedPath = ConfigMapper::get('FILE_DIR') . DIRECTORY_SEPARATOR . ConfigMapper::get('FILE_SUB_DIR') . DIRECTORY_SEPARATOR . $savedFileHash . '.' . $this->uploadExt;

        if ( ! @rename($this->uploadPartialFile, ConfigMapper::get('UPLOAD_PATH') . DIRECTORY_SEPARATOR . $this->savedPath) ) {
            return false;
        }
    }

    return $this->savedPath;
}

未能复现你的情况,上传的文件是同样的文件名和扩展名时,会发生覆盖现象。我在同一个表单两个字段,分别上传test1.txt和test2.txt,内容分别是123和456,检查未发现覆盖。
