php - Creating a folder when I run file_put_contents()

Question

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);

after I tried this one, I get error result.

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

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

Is there a way to solve this problem?

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

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);

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.

Example with recursive and directory permissions set to 777:

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