It would also be helpful to tell us what versions of PHP and SWIG you
are using. I'm guessing some version of PHP5 since you use "-php5"
below.

I don't think this is causing you problems, but it would be better to
compile and link with either g++ *OR* c++ (i.e. use the same one in
both cases).

Do you mean "example1.so" here? That's what you compiled above and try
to load below.

(As you seem to have realised from your follow-up email) you need the
PHP wrapper to be included:
include 'example1.php';
This will dl the shared object for you if it isn't already loaded, so
you don't need to do that yourself.

Sounds like php failed to load example1.so.
Try this from CLI php:
php5 -r 'include "example1.php"; $v = new Example1();'
If that works, then it's some difference in the apache environment.
Look in apache's error_log for clues. A random guess - perhaps your
umask is very restrictive, so example1.so isn't readable by the web
server user.
