Webfaction/Opalstack difference: DOCUMENT_ROOT trailing slash

ttavoy

At Webfaction, PHP DOCUMENT_ROOT has no trailing slash; here it does. Is one right and one wrong or are they both right?

https://www.php.net/manual/en/reserved.variables.server.php has an opinion:
Data: $_SERVER['DOCUMENT_ROOT'] Data type: String Purpose: Get the absolute path to the web server's document root. No trailing slash.

ttavoy I think we might be doing the wrong thing by including it. Will follow up here if we change it.

ttavoy we've just rolled out new config with trailing slash on document root.

I've always found that you should never presume that a variable will or will not have a trailing slash. In most cases, I build a custom function which takes multiple ...arguments, and combine them to generate the path. In other cases, I just always add the slash as I've never seen a double forward slash cause issues. In linux, the OS automatically knows what to do with it.
