Configuration of the 1,smarty cache:
$smarty->cache-dir= "directory name"; Create a cache directory name
$smarty->caching=true; Cache is turned on, false when caching is not valid
$smarty->cache_lifetime=60; Cache time in seconds
Use and purge of 2,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
$marty->clear_cache ("index.php", cache_id); Clear cache of the specified ID in index.php
Local cache for 3,smarty
The first: The Insert_ function is not cached by default, and this property cannot be modified
How to use: Example
In index.php,
function Insert_get_time () {
Return Date ("y-m-d h:m:s");
}
In Index.html,
{Insert Name= "Get_time"}
The second one: Smarty_block
Defines a block:smarty_block_name ($params, $content, & $smarty) {return $content;}//name represents the domain name of the zone
Register BLOCK: $smarty->register_block (' name ', ' Smarty_block_name ', false); The third parameter, False, indicates that the zone is not cached
Template notation: {name} content {/name}
Written as Block plugin:
1) Define a plug-in function: block.cacheless.php, placed in the Smarty plugins directory
The contents of block.cacheless.php are as follows:
function smarty_block_cacheless ($param, $content, & $smarty) {
return $content;
}
?>
2) Writing Programs and templates
Example program: testcacheless.php
Copy the Code code as follows:
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 handle caching using a custom function
Such as:
$smarty->cache_handler_func = "Mycache";
function Mycache ($action, & $smarty _obj, & $cache _content, $tpl _file=null, $cache _id=null, $compile _id=null) {
}
The function is generally rooted in the $action to determine the current operation of the cache:
Switch ($action) {
Case "read"://Read Cache contents
Case "Write"://write Cache
Case "clear"://Empty
}
General use of MD5 ($TPL _file. $cache _id. $compile _id) as the only cache_id
If required, use gzcompress and gzuncompress to compress and decompress
The above describes what smartlmage on means the cache application in the PHP smarty template engine, including the content of what the Smartlmage on is about, and hopefully a friend interested in the PHP tutorial will be helpful.
