请看此文章结尾处的代码片断...

当试图使用 move_uploaded_files 将 tmp 文件移动到另一个目录时,我总是会收到一个0的错误代码。 我确认目录存在, 权限设置为 775 。 我还检查了服务器管理员, 他说他没有看到错误日志中的任何错误, 从而可以解释我的问题 。

使用 move_uploaded_files 时如何绕过 0 的错误代码?

$audio_dir  = "/mbc/data/audio/";

if (isset($_POST[ upload_audio ])) {

    $title      = mysql_real_escape_string($_POST[ audio_title ]);
    $category   = mysql_real_escape_string($_POST[ audio_category ]);
    $audio_name = basename($_FILES[ audio_file ][ name ]);
    $uploadfile = $audio_dir.$audio_name;

    $query = mysql_query("SELECT COUNT(*) FROM media where path =  " . $audio_name . " ");
    $result = mysql_result($query, 0, 0);

    if (($title ==   ) || ($title == NULL) ||
        ($category ==   ) || ($category == NULL) ||
        ($audio_name ==   ) || ($audio_name == NULL)) {
        echo "<span class= error >Title, Category and Audio file are required fields</span>";                            
    } else if ($result > 0) {
    echo "<span class= error >Media $audio_name already exists - please upload with a different name</span>";

        echo "<span class= error >Category can only have letters (no spaces, commas, numbers, etc...)</span>";              
    } else if (ctype_alnum(substr($audio_name, 0, strpos($audio_name,  . ))) === false) {
    echo "<span class= error >Bad filename - $audio_name - can only contain letters and numbers (i.e.  HowGreatThouArt.mp3 )</span>";
