Getting PHP to work

[Darin Perusich]

are you running php as a module or built into apache? if you're running 
as a module apache needs to be compile with mod_so enabled, check this 
by running httpd -l and look for mod_so. if php is built as part of 
apache httpd -l will have mod_php4.c listed as well. apache also needs 
to know how to interpret php script from plain html. there should be a 
line in httpd.conf that reads at least "AddType application/x-httpd-php 
.php", this will only read .php pages though. using "AddType 
application/x-httpd-php .php .php3 .htm .html" will allow php to render 
all files ending with these extensions.

i'd also recommend setting the DirectoryIndex directive to 
"DirectoryIndex index.html index.htm login.html login.htm index.phtml 
index.php index.php3". this way if you use index.php instead of 
index.html that page will load by default.

also the line you entered into mozilla's location will cause mozilla to 
read the file as if it where a text file, you've bypassed the webserver. 
doing something like http://localhost/~bigbird/pgm/phpinfo.php would be 
more approiate.
