PHP is a module in Apache, which was configured using the following command...
./configure \
--prefix=/usr/local/apache \
--enable-so \
--enable-module=rewrite \
--enable-module=auth_digest \
--enable-module=vhost_alias \
--enable-module=log_referer \
--enable-module=php4 \
--enable-ssl \
--with-ssl=/usr/local/ssl/install/openssl
Not sure how to find where the new binary is going. I used "locate php" to find the following locations...
/usr/local/bin/php/
/usr/local/include/php/
/usr/local/lib/php
/usr/local/src/php-4.3.2
