php move_上传的_文件（）

因此，我正在测试w3schools网站上的move_uploaded_file（）php脚本。 这是我的密码

if ($_FILES["file"]["size"] < 2000000)
{
    if ($_FILES["file"]["error"] > 0)
        echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    else
    {
        echo "Upload: " . $_FILES["file"]["name"] . "<br />";
        echo "Type: " . $_FILES["file"]["type"] . "<br />";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
        echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

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

if（$\u文件[“文件”][“大小”]<2000000）
{
如果（$\u文件[“文件”][“错误”]>0）
回显“返回代码：”.$\u文件[“文件”][“错误”]。“
”；
其他的
{
echo“上传：.”文件[“文件”][“名称”]。“
”；
回显“类型：”.$\u文件[“文件”][“类型”]。“
”；
回显“大小：”（$_文件[“文件”][“大小”]/1024）。“Kb
”；
回显“临时文件：”.$\u文件[“文件”][“tmp\u名称”]。“
”；
如果（文件存在（“/var/www/upload/”$\u文件[“文件”][“名称”]））
{
echo$\u文件[“文件”][“名称”]。“已存在。”；
}
elseif（移动上传的文件（$文件[“文件”][“tmp文件名”]，“/var/www/upload/”$fileName））
echo“存储在：”../var/www/upload/”$fileName中；
}
}
其他的
回显“无效文件”；

问题是

如果（move_upload_file（$_FILES[“file”][“tmp_name”]，“/var/www/upload/”$fileName））

始终返回false，但文件似乎存储在服务器上的

tmp

文件夹中（例如：

/tmp/php8rrKoW

）。当我检查

tmp

文件夹时，文件不在那里。（它应该在脚本执行完毕后被删除。）我也没有看到

/php8rrkoW

文件夹。我不确定它是否应该在那里。我使用

chmod

将

tmp

文件夹和

/var/www/upload/

的权限设置为

777

，但我不确定是否应该将所有者设置为

apache

。因此，我想知道为什么文件没有复制到

/var/www/upload

，以及是否有办法测试这一点。

似乎您应该使用/upload/而不是/var/www/upload/，因为您已经在可访问网站的主目录中

你也可以参考 或API：

让我知道这是否有效

要将文件移动到的目标目录应由Web服务器用户写入。另外，不要忘记某些Web服务器在changeroot内部运行，因此可能不需要部分目标路径。PHP帮助文档还说，您应该检查HTLM表单，以确保它是enctype='multipart/formdata'

最后一点：$filename是在哪里定义的
