运行file_put_contents()时创建一个文件夹 [英] Creating a folder when I run file_put_contents()

问题描述

我从网站上上传了很多图像，需要以更好的方式组织文件. 因此，我决定按月创建一个文件夹.

I have uploaded a lot of images from the website, and need to organize files in a better way. Therefore, I decide to create a folder by months.

$month  = date('Yd')
file_put_contents("upload/promotions/".$month."/".$image, $contents_data);

尝试了这一步之后，我得到了错误结果.

after I tried this one, I get error result.

消息:file_put_contents(upload/promotions/201211/ang232.png):无法打开流:没有这样的文件或目录

Message: file_put_contents(upload/promotions/201211/ang232.png): failed to open stream: No such file or directory

如果我尝试仅将文件放入"existant"文件夹中，则可以正常工作.但是，它无法创建新文件夹.

If I tried to put only file in exist folder, it worked. However, it failed to create a new folder.

有没有办法解决这个问题?

Is there a way to solve this problem?

推荐答案

file_put_contents() 不会创建目录结构.只有文件.

file_put_contents() does not create the directory structure. Only the file.

您将需要在脚本中添加逻辑以测试 month 目录是否存在.如果不是，请先使用 mkdir() .

You will need to add logic to your script to test if the month directory exists. If not, use mkdir() first.

if (!is_dir('upload/promotions/' . $month)) {
  // dir doesn't exist, make it
  mkdir('upload/promotions/' . $month);
}

file_put_contents('upload/promotions/' . $month . '/' . $image, $contents_data);

更新:mkdir()接受$recursive的第三个参数，它将创建 any 缺少的目录结构.如果您需要创建多个目录，可能会很有用.

Update: mkdir() accepts a third parameter of $recursive which will create any missing directory structure. Might be useful if you need to create multiple directories.

将递归和目录权限设置为777的示例:

Example with recursive and directory permissions set to 777:

mkdir('upload/promotions/' . $month, 0777, true);
