PHP move_uploaded_file（）以deosn't工作

Question

我想上傳文件到我的樹莓派3.我安裝Apache和PHP，這是網頁的index.php的內容：

<form enctype="multipart/form-data" action="index.php" method="POST"> 
<input type="hidden" name="MAX_FILE_SIZE" value="5000000" /> 
Send this file: <input name="userfile" type="file" /> 
<input type="submit" value="Send File" /> 
</form> 

<?php 
if ($_FILES["userfile"]["size"] != 0 && $_FILES["userfile"]["tmp_name"] != "") 
{ 
    $uploaddir = "/var/www/html/"; 
    $uploadfile = $uploaddir . $_FILES["userfile"]["name"]; 
    try 
    { 
     echo '<pre>'; 
     if (move_uploaded_file($_FILES["userfile"]["tmp_name"], $uploadfile)) 
     { 
      echo "File is valid, and was successfully uploaded.\n\n"; 
     } 
     else 
     { 
      echo "File upload failed\n\n"; 
     } 
    } 
    catch (Exception $e) { echo $e->getMessage()."\n"; } 

    echo "Array content:\n"; 
    print_r($_FILES); 

    print "</pre>"; 
} ?> 

當我上傳一個文件，甚至包含一些字節的文本文件，move_uploaded_file（）返回false並且文件沒有上傳，但是沒有拋出異常並且$_FILES["userfile"]["error"]的值爲0.文件夾/var/www/html/的權限爲drwxr-xr-x，所以它們應該夠了吧？

顯然它已經足以運行sudo chmod 777 /var/www/html/。我很確定我已經做到了，但可能我沒有正確做到。

Answer 2

你缺少目錄的創建功能..我相信你忘了在需要的名稱上創建一個目錄..你需要權限上傳你請求的文件..試試這個並告訴我結果..如果可能的話建立一個內部目錄，以緩解烏爾概率..其他更改使用chmod目錄權限..感謝和問候

<form enctype="multipart/form-data" action="index.php" method="POST"> 
<input type="hidden" name="MAX_FILE_SIZE" value="5000000" /> 
Send this file: <input name="userfile" type="file" /> 
<input type="submit" value="Send File" /> 
</form> 

<?php 
if ($_FILES["userfile"]["size"] != 0 && $_FILES["userfile"]["tmp_name"] != "") 
{ 
    $uploaddir = "./html/"; // i changed it to relative pathname, it will be easy if u r uploading this code to server or so 
    if (!file_exists($uploaddir)) { 
     mkdir($uploaddir, 0777); 
    } 
    $uploadfile = $uploaddir . $_FILES["userfile"]["name"]; 
    try 
    { 
     echo '<pre>'; 
     if (move_uploaded_file($_FILES["userfile"]["tmp_name"], $uploadfile)) 
     { 
      echo "File is valid, and was successfully uploaded.\n\n"; 
     } 
     else 
     { 
      echo "File upload failed\n\n"; 
     } 
    } 
    catch (Exception $e) { 
     echo $e->getMessage()."\n"; 
    } 

    echo "Array content:\n"; 
    print_r($_FILES); 


    print "</pre>"; 
} ?> 

試圖代碼之前嘗試設置目錄的權限，試試這個在烏爾終端。 。
