The principle of page static before Smarty cache control _php Technique

Can be set in display

$smarty->display ("Demo.tpl", $_server[request_uri]) to implement a template with multiple caches.

Now that the file has been cached, we can go to the cache file, do not loop the execution of the connection database, query. Using a function in Smatry to judge

$smarty->iscached (Demo.tpl ",", $_server[request_uri]) The default value is "True" the template here is the same as display.

There's a difference between the Smarty3 and the Smarty2.

$smarty->is_cached (Demo.tpl ",", $_server[request_uri]) smarty2

$smarty->iscached (Demo.tpl ",", $_server[request_ur]i) smarty3

But there are parts of the template that do not need to be cached, for example: User login, and the comments section of the article does not need to be cached, so we solve

1, in the PHP file, if you do not need to cache the data to be placed outside the iscached judgment.

2. In the template if you do not need to cache the part of the <{nocache}>........<{/nocache}> between.
