I use env -i to start php-cgi else php environment gets polluted by bash env.
One example is if you run pam-tmpdir things that uses TMPDIR will fail.
/etc/default/php-fastcgi
#
# Settings for php-cgi in external FASTCGI Mode

# Should php-fastcgi run automatically on startup? (default: no)
START=yes
# Init script verbose output.
# INIT_VERBOSE=yes
# Listen type (default: tcp)
PHP_FCGI_TYPE=tcp
# Which user runs PHP? (default: www-data)
PHP_FCGI_USER=www-data
# Host and TCP port for FASTCGI-Listener (default: localhost:9000)
PHP_FCGI_HOST=127.0.0.1
PHP_FCGI_PORT=9000
# Unix socket.
PHP_FCGI_SOCKET=/var/run/php-fastcgi/php-fastcgi.sock
