Applications related to smarty caching

$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, unit is seconds

2. Use and clear Smarty cache

$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 of the specified ID in index.php

3. Smarty’s local cache The first one: The insert_ function does not cache by default, and this attribute cannot be modified. How to use: 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 means that this area is not cached Template writing: {name}content{/name} Written as a block plug-in: 1) Define a plug-in function: block.cacheless.php and place it in the smarty plugins directory The content of block.cacheless.php is as follows:

function smarty_block_cacheless($param, $content, &$smarty) {
return $content;
}
?>

2) Write program and template 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 Already cached: {$smarty.now}
{cacheless} Not cached:{$smarty.now} {/cacheless} 4. Custom cache Set cache_handler_func to use a custom function to handle the cache like:

$smarty->cache_handler_func = "myCache";
function myCache($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, use gzcompress and gzuncompress to compress and decompress.
