Require_once PHP Error
Maybe you are in the wrong work directory. Its a bad idea to rely on it (except you explictly want to access it) anyway. Use
require __DIR__ . '/../fruit.php';
or with pre-5.3
require dirname(__FILE__) . '/../fruit.php';
Remind, that paths starting with ..
, or .
are not resolved against the include-path, but only against the current work directory.
Remember that in the second case, you're specifying a path, but in the first case it uses your includes path. Perhaps rather than explicitly specifying .. in the second case, you case modify your include path.
I know the question is old, but it is still relevant.
In my experience, the "open_basedir" directive is most likely to cause this issue.
