PHP緩衝整合庫phpFastCache學習教程

phpFastCache是一個開源的PHP緩衝庫，只提供一個簡單的PHP檔案，可方便整合到已有項目，支援多種緩衝方法，包括：apc, memcache, memcached, wincache, files, pdo and mpdo。可通過簡單的API來定義緩衝的有效時間。

代碼如下

複製代碼

<?php // In your config file include("phpfastcache/phpfastcache.php"); phpFastCache::setup("storage","auto"); // phpFastCache support "apc", "memcache", "memcached", "wincache" ,"files", "sqlite" and "xcache" // You don't need to change your code when you change your caching system. Or simple keep it auto $cache = phpFastCache(); // In your Class, Functions, PHP Pages // try to get from Cache first. product_page = YOUR Identity Keyword $products = $cache->get("product_page"); if($products == null) {     $products = YOUR DB QUERIES || GET_PRODUCTS_FUNCTION;     // set products in to cache in 600 seconds = 10 minutes     $cache->set("product_page", $products,600); } // Output Your Contents $products HERE

提高cURL和API調用效能

代碼如下

複製代碼

<?php include("phpfastcache/phpfastcache.php"); $cache = phpFastCache("memcached"); // try to get from Cache first. $results = $cache->get("identity_keyword") if($results == null) {     $results = cURL->get("http://www.youtube.com/api/json/url/keyword/page");     // Write to Cache Save API Calls next time     $cache->set("identity_keyword", $results, 3600*24); } foreach($results as $video) {     // Output Your Contents HERE }

全頁緩衝

代碼如下

複製代碼

<?php // use Files Cache for Whole Page / Widget // keyword = Webpage_URL $keyword_webpage = md5($_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].$_SERVER['QUERY_STRING']); $html = __c("files")->get($keyword_webpage); if($html == null) {     ob_start();     /*         ALL OF YOUR CODE GO HERE         RENDER YOUR PAGE, DB QUERY, WHATEVER     */     // GET HTML WEBPAGE     $html = ob_get_contents();     // Save to Cache 30 minutes     __c("files")->set($keyword_webpage,$html, 1800); } echo $html;

掛件緩衝

代碼如下	複製代碼
<?php // use Files Cache for Whole Page / Widget $cache = phpFastCache("files"); $html = $cache->widget_1; if($html == null) {     $html = Render Your Page || Widget || "Hello World";     // Save to Cache 30 minutes     $cache->widget_1 = array($html, 1800); } echo or return your $html;

同時使用多種緩衝

代碼如下

複製代碼

<?php // in your config files include("phpfastcache/phpfastcache.php"); // auto | memcache | files ...etc. Will be default for $cache = __c(); phpFastCache::$storage = "auto"; $cache1 = phpFastCache(); $cache2 = __c("memcache"); $server = array(array("127.0.0.1",11211,100), array("128.5.1.3",11215,80)); $cache2->option("server", $server); $cache3 = new phpFastCache("apc"); // How to Write? $cache1->set("keyword1", "string|number|array|object", 300); $cache2->keyword2 = array("something here", 600); __c()->keyword3 = array("array|object", 3600*24); // How to Read? $data = $cache1->get("keyword1"); $data = $cache2->keyword2; $data = __c()->keyword3; $data = __c()->get("keyword4"); // Free to Travel between any caching methods $cache1 = phpFastCache("files"); $cache1->set("keyword1", $value, $time); $cache1->memcache->set("keyword1", $value, $time); $cache1->apc->set("whatever", $value, 300); $cache2 = __c("apc"); $cache2->keyword1 = array("so cool", 300); $cache2->files->keyword1 = array("Oh yeah!", 600); $data = __c("memcache")->get("keyword1"); $data = __c("files")->get("keyword2"); $data = __c()->keyword3; // Multiple ? No Problem $list = $cache1->getMulti(array("key1","key2","key3")); $cache2->setMulti(array("key1","value1", 300),                   array("key2","value2", 600),                   array("key3","value3", 1800),                   ); $list = $cache1->apc->getMulti(array("key1","key2","key3")); __c()->memcache->getMulti(array("a","b","c")); // want more?
