Smarty配置緩存時(shí)間

<?php
require('Smarty.class.php');
$smarty = new Smarty;

// 使用$smarty->cacheLifetime()可以更精確定義緩存時(shí)間

$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);

$smarty->display('index.tpl');
?>

<?php
require('Smarty.class.php');
$smarty = new Smarty;

// 讓每個(gè)緩存的過期時(shí)間都可以在display執(zhí)行前單獨(dú)設(shè)置。
$smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);

// 設(shè)置index.tpl的過期時(shí)間為5分鐘
$smarty->setCacheLifetime(300);
$smarty->display('index.tpl');

// 設(shè)置home.tpl的過期時(shí)間為1小時(shí)
$smarty->setCacheLifetime(3600);
$smarty->display('home.tpl');

// 注意：當(dāng)$caching設(shè)置了Smarty::CACHING_LIFETIME_SAVED后，
// 下面的$cache_lifetime將不會(huì)起效。
// home.tpl已經(jīng)設(shè)置了過期時(shí)間為1小時(shí)，
// 所以不會(huì)再遵循下面的$cache_lifetime值，
// home.tpl的過期時(shí)間還是1小時(shí)。
$smarty->setCacheLifetime(30); // 30 秒
$smarty->display('home.tpl');
?>

<?php
require('Smarty.class.php');
$smarty = new Smarty;

$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
$smarty->setCompileCheck(false);

$smarty->display('index.tpl');

if(!$smarty->isCached('index.tpl')) {
	// 找不到緩存，這里進(jìn)行一些賦值操作
    $contents = get_database_contents();
    $smarty->assign($contents);
}

$smarty->display('index.tpl');
?>

<?php
require('Smarty.class.php');
$smarty = new Smarty;

$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);

// 僅刪除index.tpl的緩存
$smarty->clearCache('index.tpl');

// 刪除全部緩存
$smarty->clearAllCache();
