Usage of PHP cache integration library phpFastCache, phpphpfastcache

The example in this article describes the usage of the PHP cache integration library phpFastCache. Share it with everyone for your reference. The specific analysis is as follows:

phpFastCache is an open source PHP caching library that only provides a simple PHP file, which can be easily integrated into existing projects. It supports multiple caching methods, including: apc, memcache, memcached, wincache, files, pdo and mpdo. The cache validity time can be defined through a simple API.

Copy code The code is as follows:

//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

Improve cURL and API call performance

Copy code The code is as follows:

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
}

Full page caching

Copy code The code is as follows:

// 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;

Widget cache

Copy code The code is as follows:

// 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;

Use multiple caches simultaneously

Copy code The code is as follows:

// 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"));
