这篇文章主要介绍了PHP缓存集成库phpFastCache用法,包括基本用法的分析与操作实例,在PHP项目开发中非常具有实用价值,需要的朋友可以参考下
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。
代码如下:
- <?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调用性能,代码如下:
- <?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
- }
全页缓存,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,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,代码如下:
- <?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"));
