The Apache Migration HOWTO had the answer.
When configuring Apache for PHP, there are three differences between Apache 1.3 and Apache 2.0.
1. The standard httpd.conf now contains Include conf.d/*.conf. The file conf.d/php.conf contains the LoadModule statement for php.
2. Instead of the AddType application/x-httpd-php .php, you must include the following in httpd.conf (or php.conf)
<Files *.php> SetOutputFilter PHP SetInputFilter PHP </Files>
3. My test file which contained <? phpinfo() ?> must now contain instead <?php phpinfo() ?> as short open tags are now disabled.
An interesting distraction I discovered was this: php comes with two model configuration files, php.ini-dist, and php.ini-recommended. Apache2 /PHP4 was configured with php.ini-recommended, Netscape 7 running on Solaris could not display it, but Netscape 4.79 could. The problem disappeared when I used php.ini-dist.
php.ini-recommended contains the comments
; This is the recommended, PHP 4-style version of the php.ini-dist file. It
; sets some non standard settings, that make PHP more efficient, more secure,
; and encourage cleaner coding.
; The price is that with these settings, PHP may be incompatible with some
; applications, and sometimes, more difficult to develop with. Using this
; file is warmly recommended for production sites.
So, be careful with php.ini-recommended!
