You guessed right. PHP usually runs under a user with less permissions
(www, user, etc..). You are probably logged in as a user with permissions
to access that mounted drive while PHP isn't. Both fixes are ugly, but what
I would recommend is giving permission to those files as opposed to giving
PHP user more power.
