PHP move_uploaded_file forcely賦予了新的名字

我試圖使用PHP上傳文件，代碼snipptPHP move_uploaded_file forcely賦予了新的名字

$upload_path = "/var/upload/" . $_FILES['mfile']['name']; 
if(move_uploaded_file($_FILES['mfile']['tmp_name'], $upload_path)) 
    echo "file uploaded"; 
else 
    echo "upload failed";

注意：在/ var/upload目錄存在並且具有777權限。

的代碼打印「上傳失敗」

當我檢查/ var/upload目錄，有文件f_505bf77bd8a0f_mypdf.pdf。什麼地方出了錯？

添加日誌（按照由loler要求）：

    array(5) { 
    ["name"]=&gt; 
    string(23) "mypdf.pdf"

什麼是你的['upload_tmp_dir']（http://us.php.net/manual/en/ini.core.php#ini.upload- TMP-DIR）？你確定你看到的這個文件與你的上傳有關，而不是來自其他地方？（如果您信任用戶提供的文件名太多，您最終會覆蓋現有文件。） – DCoder

您可以檢查Apache錯誤日誌嗎？ – F0G

DCoder，我是110％;-)確實如此。因爲我刪除目錄中的所有文件並嘗試腳本。我甚至驗證了文件打開目錄。 – Elisa

試試這個代碼，上傳您的文件..

if (file_exists("/var/upload/" . $_FILES["file"]["name"])) 
    { 
    echo $_FILES["file"]["name"] . " already exists. "; 
    } 
else 
    { 
    move_uploaded_file($_FILES["file"]["tmp_name"], 
    "/var/upload/" . $_FILES["file"]["name"]); 
    echo "Stored in: " . "/var/upload/" . $_FILES["file"]["name"]; 
    }

肯定沒有該名稱的文件 – Elisa

在您的var_dump()有$_FILES["file"]["name"]的長度是23，但它應該是9.所以試試trim這個字符串。的

$upload_path = "/var/upload/" . $_FILES['mfile']['name'];

會轉而寫

$upload_path = "/var/upload/" . trim($_FILES['mfile']['name']);
