Editez votre fichier php.ini file, ajoutez le chemin de la bibliothèque Smarty et redémarrez les serveur web.

include_path = ".;c:\chemin\vers\smarty\"

INSTALLATION (quick):

* copy the files under the libs/ directory to a directory that is in your PHP
include_path, or set the SMARTY_DIR constant and put them in this directory.
(if you upgrade from versions before 2.5.0 be aware that up to Smarty 2.4.2
all necessary files where in the distribution's root directory, but are now
in libs/.)

* for each application using Smarty, create a "templates", "configs", and a
"templates_c" directory, be sure to set the appropriate directory settings in
Smarty for them. If they are located in the same directory as your
application, they shouldn't need to be modified. Be sure the "templates_c"
directory is writable by your web server user (usually nobody). chown
nobody:nobody templates_c; chmod 700 templates_c You can also chmod 777 this
directory, but be aware of security issues for multi-user systems. If you are
using Smarty's built-in caching, create a "cache" directory and also chown
nobody:nobody.

* setup your php and template files. A good working example is in the on-line
documentation.

* TECHNICAL NOTE: If you do not have access to the php.ini file, you can change
non-server settings (such as your include_path) with the ini_set() command.
example: ini_set("include_path",".:/usr/local/lib/php");
