警告：move_uploaded_file（）：无法将“文件”移至“文件夹”

Question

我尝试将图像上传到本地主机上的目录。

这是我的php文件中的部分，会导致错误：

if (move_uploaded_file($tmp_name, "/Users/sandro/Documents/bildgalerie/uploads")) {
    echo "The file " . basename($filename) . " has been uploaded";
} else {
    echo "error";
}

如果我加载页面，则会得到以下信息：

Warning: move_uploaded_file(): Unable to move '/private/var/folders/np/sln14hvn3tsbzc4kpjjtp17c0000gn/T/phppJbFJK' to '/Users/sandro/Documents/bildgalerie/uploads' in /Users/sandro/Documents/bildgalerie/control/upload.php on line 31
