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。
// 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
$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
// 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
$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
$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); $cache1->memcache->set("keyword1",$time); $cache1->apc->set("whatever",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","key3")); __c()->memcache->getMulti(array("a","b","c"));
