Cache application in eset smart security php smarty template engine

1. Smarty cache configuration:

Copy the code The code is as follows:

$smarty->cache-dir="directory name"; //Create cache directory name
$smarty->caching=true ; //Enable caching. When it is false, the cache will be invalid.
$smarty->cache_lifetime=60; //Cache time, in seconds

2, Smarty cache usage and clearing

Copy code Code As follows:

$marty->display("cache.tpl",cache_id); //Create a cache with ID
$marty->clear_all_cache(); //Clear all caches
$marty->clear_cache ("index.php"); //Clear the cache in index.php
$marty->clear_cache("index.php',cache_id); //Clear the cache with the specified ID in index.php

3, Smarty's local cache
The first one: The insert_ function is not cached by default. This attribute cannot be modified.
Usage: Example
index.php,
function insert_get_time(){
return date("Y-m-d H:m:s ");
}
index.html,
{insert name="get_time"}
Second: smarty_block
Define a block: smarty_block_name($params,$content, &$smarty){return $content;} / /name represents the area name
Register block:$smarty->register_block('name', 'smarty_block_name', false); //The third parameter false indicates that the area is not cached
Template writing method: {name}content{/name }
Written as a block plug-in:
1) Define a plug-in function: block.cacheless.php and place it in smarty’s plugins directory
The content of block.cacheless.php is as follows:
function smarty_block_cacheless($param, $ content, &$smarty) {
return $content;
}
?>
2) Write programs and templates
Sample program: testCacheLess.php
include('Smarty.class.php');
$smarty = new Smarty;
$smarty->caching=true;
$smarty->cache_lifetime = 6;
$smarty->display('cache.tpl');
?>
Template used: cache.tpl
Cached: {$smarty.now}

{cacheless}
Not cached: {$smarty.now}
{/cacheless}
4 Custom cache
Set cache_handler_func to use custom Function handling cache
For example:
$smarty->cache_handler_func = "myCache";
function myCache($action, &$smarty_obj, &$cache_content, $tpl_file=null, $cache_id=null, $compile_id=null){
}
This function is generally based on $action to determine the current operation of the cache:
switch($action){
case "read"://read cache content
case "write"://write cache
case " clear"://clear
}
Generally use md5 ($tpl_file.$cache_id.$compile_id) as the only cache_id
If necessary, you can use gzcompress and gzuncompress to compress and decompress
