本文介绍了一个常见的PHP上传文件时遇到的问题，即上传的文件名在GBK编码环境下显示为乱码。通过使用iconv函数将文件名从UTF-8转换为gb2312，成功解决了中文文件名的乱码问题。

原始代码：

if(!move_uploaded_file($book_image['tmp_name'], $book_image['name'])){
    $err_msg = "Error moving the file to its destination, " .
        "please try again <a href='{$upload_page}'>here</a>.";
}

可能是move_uploaded_file这个函数不考虑文件编码，硬编码为GBK处理的，导致出错．

代码改进：要用到iconv这个函数

if(!move_uploaded_file($book_image['tmp_name'], iconv("UTF-8","gb2312",$book_image['name']))){
    $err_msg = "Error moving the file to its destination, " .
        "please try again <a href='{$upload_page}'>here</a>.";
}

这样就能保存到正确的中文文件名了．
