\$cache_dir {#variable.cache.dir}
This is the name of the directory where template caches are stored. By
default this is ./cache, meaning that Smarty will look for the
cache/ directory in the same directory as the executing php script.
This directory must be writeable by the web server, see
install for more info.
You can also use your own custom cache implementation
to control cache files, which will ignore this setting. See also
$use_sub_dirs.
Note
This setting must be either a relative or absolute path. include_path is not used for writing files.
Note
It is not recommended to put this directory under the web server document root.
Note
As of Smarty 3.1 the attribute \$cache_dir is no longer accessible directly. Use
getCacheDir()andsetCacheDir()instead.
See also getCacheDir(),
setCacheDir(), $caching,
$use_sub_dirs,
$cache_lifetime,
$cache_modified_check and the
caching section.
