PHP fwrite to windows absolute path

I have various websites that share directories on windows server, running PHP7.2.

The structure is:

c:\websites\domain1.com\app -> Admin website
c:\websites\domain1.com\clients\clientAdomain.com -> Client A website
c:\websites\domain1.com\clients\clientBdomain.com -> Client B website
c:\websites\domain1.com\clients\clientCdomain.com -> Client C website
etc

Each website has subfolders

Any scripts that are shared amongst all the folders throughout all the websites are stored in c:\websites\common and "included" where necessary

I also have a "logs" folder at
c:\websites\logs

I am trying to find a way of using fwrite with an absolute path to always write any logs to the logs folder, from wherever the scripts is called from. Ideally I'd like to use something like

fopen("c:\websites\logs\log.txt","+a");

But I don't think that it works.

Any advice would be appreciated

You are running apache rather than iis?
Usually each instance logs to its own stracture.
It is isolating each site

Presumably, your php has a database back end you could use access to the db, though it will add to the resource consumption.

In C type languages the '\' is an escape character it means use the '\' in combination with the next character to define another (usually non-printable) character.
So \t (tab) \n (newline / linefeed), \r (carriage return)
When you need to use the '\' as a backslash then escape it with another '\'

C:\\path

Open in new window

Personally I don't like defining constant strings inside the function that uses them - makes maintaining them a pain.
Recommendation:
In your common / config file

define('LOGPATH', "c:\\websites\\logs\\");

Open in new window

Then in your use case

fopen(LOGPATH . "log.txt","+a");

Open in new window

Thanks

The double escaping got me!
