Testing apache1.3 and apache2 in parallel with PHP
Our web-hosting service is still on apache1.3, but we've decide it's
finally time to switch to apache2.
We would like to have both apache daemons running in parallel for a
while to test out the setup. I have apache1.3 still listening on port
80; apache2 listens on a different port for testing purposes.
Several users use PHP. By default, PHP is disabled. The user enables it
on a per-directory basis using php_flag engine on.
I understand php_flag is not supported in apache2, and thus it won't
serve content from any directory where that instruction is in the
.htaccess file. I haven't been able to figure out how to duplicate the
setup we have with apache2--namely, PHP disabled by default, by
overriden on a per-directory basis. I've tried php_value engine 1, but
that doesn't seem to work. In any event, I'm concerned anything I do to
make the htaccess files compatible with apache2 will break compatibility
with apache1.3, so I won't be able to have everything running in
parallel for testing.
Two questions:
(1) How do disable PHP globally but enable per-directory in .htaccess
for apache2?
(2) Any way to do #1 that will allow things to continue to work as
before in apache1.3?
Thanks in advance for any tips.

I just recently fixed couples of site's setup by adding some php_flag
session.auto_start Off directives. IIRC for broken Joomla setup of some
customers after our migration. This was few days ago, running Lenny
(where only apache2 is available). So, 100%, it's supported.

AFAIR, there's no php_value, but php_admin_value instead.

With all the above being said, I'm not sure you could enable the php
engine in a .htaccess. That would need some testings, I guess.

I was basing that on this:
"Note that php_flag does not work with Apache 2. Neither does on / off —
you must use 0 (off) or 1 (on)."

Not correct?

So it seems like the relevant command would actually be
php_admin_flag engine on

But I can't see any way to make that command work in htaccess (rather
than in the site config).

Even with these settings, I still get this in error.log:
.htaccess: php_flag not allowed here

First, you need to have a look at the AllowOverride directive of apache,
second, it seems that you are confusing php_flag and php_admin_value.
Are these 2 exactly the same? I don't think so. It's a kind of mess for
me to see all these:
I used to use only:
- php_admin_value (in my apache2.conf)
- php_flag (in my .htaccess)
Can anyone tell what's the truth about it? I'm puzzled now...

Hmmm - that's funny actually. I used this with apache2. There are
differences between Php4 and Php5 maybe. Not all values may be set this
way. Some of them have to be set in php.ini.
