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&#39;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[&#39;HTTP_HOST&#39;].$_SERVER[&#39;REQUEST_URI&#39;].$_SERVER[&#39;QUERY_STRING&#39;]); 
	$html = __c("files")->get($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"));
