wild guess says, compare your PATH and other key environment variables
(such as LD_LIBRARY_PATH) while logged in as postgres vs your other
user...  adjust the path of this other user to suit.

Apparently your php CLI binary has support for PostgreSQL compiled in,
your web server not. Resolving this highly depends on your platform;
it might be as easy as installing an RPM and restarting the web server,
or you needing to recompile PHP with PostgreSQL support compiled in.

There is no need to use trial and error - this is covered in the manuals:
http://www.postgresql.org/docs/current/static/client-authentication.html

You're trying to connect with a username of "apache" and you don't have
that set up in the database.

Stop. Make a good hot cup of tea/coffee and read through the section of
the manual mentioned above. Disable access from the internet
(listen_addresses) and set up "trust" access as a first step.

Connect as the postgres user (from psql), add a new database user (e.g.
"test") with a password (see the manuals for details). Create a database
owned by them. Now try logging in as that user - no password should be
necessary.

Edit the pg_hba.conf to require passwords for all users apart from
"postgres" which you can leave as "ident". Restart the postgresql server
and try reconnecting as your test user. You should now need a password.

If all that's working, try connecting as your test user from php. Don't
forget to check result codes when you connect to the database or send a
query etc.
