Mixing Plesk open_basedir path syntax

Plesk uses a convoluted syntax for open_basedir settings in Plesk. You can find this setting on a per-domain basis by navigating the Plesk GUI like this:

Domains -> -> PHP Settings -> Common settings ->  open_basedir

The default setting looks like this:

This breaks down as follows:

The first part, {WEBSPACEROOT}{/} means the the entire webspace root, /var/www/vhosts/ in this case. This includes httpdocs and any folder in this path.

The second part {:} is the delimiter.

The third part {TMP}{/} means the /tmp directory

Any additional paths can be added by appending a normal UNIX-style path syntax as in this example:
