With instructions from
http://benoit.noss.free.fr/php/install-php.html
I followed instructions
Be carefull there :
.Due to a bug of the Nestcape/iPlanet administration console,
you have to create a dummy shell-cgi directory (for ex:/dummy maps c:/temp)
.On the MIME Types page, add a new MIME type.
Set the Type field to type, and the content type to magnus-internal/shellcgi
In the File Suffix field, enter php,php3,php4 Click here for screenshot
Good luck
