PHP缓存的方法有很多种,常用的有memcache, memcached。现在我们来学习一个php缓存集成库phpFastCache,就是开源的,只有一个简单的php文件,就可以支持包括apc,memcache,memcached,wincache,files,pdo and mpdo等缓存方法.

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();

//开源软件:phpfensi.com

// 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"));
