我在嘗試將文件上傳到我的網絡服務器時出現錯誤。他們正在上傳正常，這是當我從文件中提取細節時，它會引發錯誤。也可以點擊上傳文件時，它把它帶來了'./filename.jpg'不'uploads/filename.jpg'上傳文件夾是/uploads/警告：filemtime（）：stat失敗
我相信這是處理文件的真實路徑，但我不確定如何解決它在錯誤的道路。
這是我使用的代碼示例。
<form enctype="multipart/form-data" action="./.upload_file.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />

<input type="submit" value="Upload" />
</form>
<table class="sortable">

那麼filemtime（）如何失敗？它返回的時間不正確嗎？它是拋出一個異常還是顯示一個錯誤，它是否會留下空白頁？ –
如果您收到'stat failed'，那麼您使用的文件名/路徑無效，或者您無權訪問文件所在的一個或多個父目錄。 –
