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。

<?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
<?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

<?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

<?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

<?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"));
