I suggested it simply because it would bypass some errors ;)

One of the major problems with Linux is the way each distribution
modifies just where it installs key applications and how it manages
them. I'm on SUSE myself and apart from a couple of attempts at other
distros when the SUSE guys just totally lost the plot, I've been with
that since version 6. My problem is installing later APACHE/PHP builds
while maintaining the stable SUSE installs ... and getting paths right
teds to be the problem.

THAT is telling me that /httpd/iliffe/i_phpinfo.php is not the path to
the file. Bit like one gets with windows where it hides the real
physical location and only gives you a 'user' view of the path. My copy
of Apache is using wwwrun:www user when it is running, so all of the
/<server name> folders and files have that user name and group, but even
with that php should be able still to read the file so I'm still
thinking the path is wrong in some way. A quick search on Fedora give
/var/www/html/ as the default where SUSE gives me /srv/www/htdocs ...

If there was a good security reason for changing the PHP5.4 machines I'm
still running then I'd move, and eaccelerator still provides all the
speed improvement I need, so I'm not surprised three quarters the world
has yet to even move to a higher version of PHP5 ... and less that 5%
are using PHP7 front facing.
