mkdir() PHP 函数在 Windows 上不起作用

Question

我已经尝试了几天，以弄清楚为什么我在以下代码中的 mkdir（） 函数不起作用。 我希望你们能够为我指出正确的方向。 我也不确定我是否需要更改 php.ini 文件中的任何内容才能让这个野兽正常工作。

function create_album()
{
try
{
    if( isset( $_SESSION['session_id'] ) && $_SESSION['permissions'] ==  0  )
    {
        if( isset( $_POST['album_name'] ) && ( file_exists( $_FILES['cover_photo']['tmp_name'] ) || is_uploaded_file($_FILES['cover_photo']['tmp_name'] ) ) )
        {
            $db = honneyconnect( ) ;
            if( mysqli_connect_error() )
            {
                throw new Exception( "Could not connect to the database") ;
            }
            else
            {
                $unique = false ;
                /*while( !$unique )
                {
                    $key = rand( )  ;
                    $query = "select * from albums where album_id = '".$key."'";
                    $result = $db->query( $query ) ;
                    if( !$result )
                    {
                        $unique = true ;
                    }
                }*/
                $key = 5 ;
                if( !mkdir( "/www/honeysproject/".$_POST['album_name']  ) )
                {

Answer 1

Windows文件系统与Linux完全不同：

if( !mkdir( "/www/honeysproject/".$_POST['album_name']  ) )

我认为这应该是：

if( !mkdir( "c:\www\honeysproject\".$_POST['album_name']  ) )

Answer 2

如果你想在Windows上执行此操作，你应该把正确的路径而不是"/www/honeysproject/"

你应该放这样的东西：

if( !mkdir( "c:\www\honeysproject\".$_POST['album_name']  ) )

两个斜杠是安全的方式
