我正在尝试删除包含所有图像的相册。存储的相册和图像的路径是../_uploads/< album_name >/< image_file >。这是我的 delete_album.php 中的代码：

    if(isset($_GET['album_id']) === true){
    $album_id = (int)$_GET['album_id'];
    $query_album_info = "SELECT `albums`.`album_id`, `albums`.`album_name`, `images`.`image_name`, `images`.`image_ext`
                        FROM `albums`
                        LEFT JOIN `images` ON `albums`.`album_id` = `images`.`album_id`
                        WHERE `albums`.`album_id` = {$album_id}
                        LIMIT 1 ";
    $album_info = mysql_query($query_album_info, $connection) or die(mysql_error());
    $row_album = mysql_fetch_assoc($album_info);

    $album = $row_album['album_name'];
    $img_file = $row_album['image_name'] . '.' . $row_album['image_ext'];

    $images = scandir("../_uploads/{$album}/");
    unset($images[0]);
    unset($images[1]);
    //echo "<pre>",print_r($images,true),"</pre>";

    foreach($images as $image){
        unlink("../_uploads/{$album}/{$image_file}");
    }
    if(rmdir("../_uploads/{$album}") === true){
        //delete all images of album from database
        $query_delete_images = "DELETE FROM `images` WHERE `album_id` = {$album_id}";
        $delete_images = mysql_query($query_delete_images) or die(mysql_error());
        if(mysql_affected_rows() == 1){         
        }else{
            redirect_to("albums.php?del_imgs=1");
        }
        //delete album from database
        $query_delete_album= "DELETE FROM `albums` WHERE `album_id` = {$album_id}";
        $delete_album= mysql_query($query_delete_album) or die(mysql_error());
        if(mysql_affected_rows() == 1){ 
            redirect_to("albums.php?delete_album=1");
        }else{
            redirect_to("albums.php?delete_error_album=1");
        }
    }else{
        redirect_to("albums.php?rmdir_error=1");
    }

}else{
    redirect_to("albums.php");
}

我从重定向到 albums.php 得到的错误消息是 [i]rmdir_error=1[/i]，所以没有图像从数据库、文件夹和相册中删除，所以 rmdir 函数不起作用因为图像仍然存在。有什么想法可能是错的吗？

您在循环中使用了错误的变量（$image_file而不是$image）。所以什么都没有被删除，当你尝试调用rmdir()时，目录不为空。

// Use the correct variable in the loop statement: changed $image to $image_file
foreach($images as $image_file) {
    // Don't attempt to remove the current directory or parent
    // Since scandir() will return those too...
    if ($image_file !== "." && $image_file !== "..") {
      unlink("../_uploads/{$album}/{$image_file}");
    }
}
