php - 警告 : filemtime(): stat failed for

Question

当我尝试将文件上传到我的网络服务器时出现错误。它们上传正常，当我从文件中提取详细信息时，它会抛出错误。此外，当单击上传的文件时，它会输入错误的路径，它会显示 './filename.jpg' 而不是 'uploads/filename.jpg' 上传文件夹是 /上传/

我相信它正在处理文件的真实路径，但我不确定如何修复它。

这是我正在使用的代码示例。

<form enctype="multipart/form-data" action="./.upload_file.php" method="post">
    <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />

尝试使用它。路径没有通过 dirArray。需要将 $path 附加到 arraypath

<form enctype="multipart/form-data" action="./.upload_file.php" method="post">
                <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
                Choose a file to upload: <input name="uploaded_file" type="file" />

              </form>
