本文实例讲述了PHP缓存集成库phpFastCache用法。分享给大家供大家参考。具体分析如下：

phpFastCache是一个开源的PHP缓存库，只提供一个简单的PHP文件，可方便集成到已有项目，支持多种缓存方法，包括：apc, memcache, memcached, wincache, files, pdo and mpdo。可通过简单的API来定义缓存的有效时间。复制代码 代码如下:<?php// In your config fileinclude("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调用性能复制代码 代码如下:<?phpinclude("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}

全页缓存复制代码 代码如下:<?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;

挂件缓存复制代码 代码如下:<?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;

同时使用多种缓存复制代码 代码如下:<?php// in your config filesinclude("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"));
