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.
// 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
$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
// 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
$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
$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"));
