[Resolved] writing linux/windows file system compatible script?

i'm writing a script with lines like that

$nav_file=getcwd() . "/$nav_link";

it's ok on linux hostings but i guess that on windows

the path returned by getcwd will be something like c:\something\bla\bla
and when i add '/$nav_link'

it will be

c:\something\bla\bla/morebla

i was just going to make a variable $slash where the user sets '/' or '\' (depending on the OS he will use the script on)

and to replace all '/' below in the script with this $slash variable

but before making all this, decided to make sure by asking here that this is the correct way to go?

you dont need to worry about using forward or backward slashes on windows.

just always use /

php will translate it for you properly on windoes, and on *nix forward slash is the proper way anyway.

but if you do NEED to specify the correct directory seperator, which is rare but theres definately times, php has a constant defined just for this

echo DIRECTORY_SEPARATOR;

well i'm someties setting the '/' as a part ot string which is later used for opening and reading dirs, so i guess it will be a problem

but DIRECTORY_SEPARATOR will definitely be ok for what i need
thank you 🙂
