When creating a log file, it cannot create a directory with the file.

chmod() does not understand dec formats

What is the expected result?

Use the native decoct() function to convert to the desired permission mode.

What do you get instead?

Correct work with directories and permission mode.

Additional info

Q	A
Yii version	2.0.48
PHP version	8.1.16
Operating system	Linux version 5.15.79.1-microsoft-standard-WSL2

updated: 02-27-2023
Fix:

1. Check under which user php is running
2. Check under which user the directories were created

For dockerfile, example:
RUN apk add -U shadow

ARG user_id=1000
RUN usermod -u $user_id www-data

It's not the problem with the "509" as you said (it's 0775 in octal), it's a problem with your filesystem and permissions on your folders. You need to correct them yourself.
