phpfastcache is a high-performance, distributed object caching system that is versatile and can be used to speed up dynamic web applications and reduce database load.
phpfastcache reduces database load to almost zero, getting faster page load times for users and better resource utilization. It's simple yet powerful.
Reduce database queries
<?<span>php </span><span>//</span><span> In your config file</span> <span>include</span>("phpfastcache/phpfastcache.php"<span>); phpFastCache</span>::setup("storage","auto"<span>); </span><span>//</span><span> 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</span> <span>$cache</span> =<span> phpFastCache(); </span><span>//</span><span> In your Class, Functions, PHP Pages // try to get from Cache first. product_page = YOUR Identity Keyword</span> <span>$products</span> = <span>$cache</span>->get("product_page"<span>); </span><span>if</span>(<span>$products</span> == <span>null</span><span>) { </span><span>$products</span> = YOUR DB QUERIES ||<span> GET_PRODUCTS_FUNCTION; </span><span>//</span><span> set products in to cache in 600 seconds = 10 minutes</span> <span>$cache</span>->set("product_page", <span>$products</span>,600<span>); } </span><span>//</span><span> Output Your Contents $products HERE</span>
Improve cURL and API call performance
<?<span>php </span><span>include</span>("phpfastcache/phpfastcache.php"<span>); </span><span>$cache</span> = phpFastCache("memcached"<span>); </span><span>//</span><span> try to get from Cache first.</span> <span>$results</span> = <span>$cache</span>->get("identity_keyword"<span>) </span><span>if</span>(<span>$results</span> == <span>null</span><span>) { </span><span>$results</span> = cURL->get("http://www.youtube.com/api/json/url/keyword/page"<span>); </span><span>//</span><span> Write to Cache Save API Calls next time</span> <span>$cache</span>->set("identity_keyword", <span>$results</span>, 3600*24<span>); } </span><span>foreach</span>(<span>$results</span> <span>as</span> <span>$video</span><span>) { </span><span>//</span><span> Output Your Contents HERE</span> }
Full page cache
<?<span>php </span><span>//</span><span> use Files Cache for Whole Page / Widget // keyword = Webpage_URL</span> <span>$keyword_webpage</span> = <span>md5</span>(<span>$_SERVER</span>['HTTP_HOST'].<span>$_SERVER</span>['REQUEST_URI'].<span>$_SERVER</span>['QUERY_STRING'<span>]); </span><span>$html</span> = __c("files")->get(<span>$keyword_webpage</span><span>); </span><span>if</span>(<span>$html</span> == <span>null</span><span>) { </span><span>ob_start</span><span>(); </span><span>/*</span><span> ALL OF YOUR CODE GO HERE RENDER YOUR PAGE, DB QUERY, WHATEVER </span><span>*/</span> <span>//</span><span> GET HTML WEBPAGE</span> <span>$html</span> = <span>ob_get_contents</span><span>(); </span><span>//</span><span> Save to Cache 30 minutes</span> __c("files")->set(<span>$keyword_webpage</span>,<span>$html</span>, 1800<span>); } </span><span>echo</span> <span>$html</span>;
Widget cache
<?<span>php </span><span>//</span><span> use Files Cache for Whole Page / Widget</span> <span>$cache</span> = phpFastCache("files"<span>); </span><span>$html</span> = <span>$cache</span>-><span>widget_1; </span><span>if</span>(<span>$html</span> == <span>null</span><span>) { </span><span>$html</span> = Render Your Page || Widget || "Hello World"<span>; </span><span>//</span><span> Save to Cache 30 minutes</span> <span>$cache</span>->widget_1 = <span>array</span>(<span>$html</span>, 1800<span>); } </span><span>echo</span> or <span>return</span> your <span>$html</span>;
Use multiple caches at the same time
<?<span>php </span><span>//</span><span> in your config files</span> <span>include</span>("phpfastcache/phpfastcache.php"<span>); </span><span>//</span><span> auto | memcache | files ...etc. Will be default for $cache = __c();</span> phpFastCache::<span>$storage</span> = "auto"<span>; </span><span>$cache1</span> =<span> phpFastCache(); </span><span>$cache2</span> = __c("memcache"<span>); </span><span>$server</span> = <span>array</span>(<span>array</span>("127.0.0.1",11211,100), <span>array</span>("128.5.1.3",11215,80<span>)); </span><span>$cache2</span>->option("server", <span>$server</span><span>); </span><span>$cache3</span> = <span>new</span> phpFastCache("apc"<span>); </span><span>//</span><span> How to Write?</span> <span>$cache1</span>->set("keyword1", "string|number|array|object", 300<span>); </span><span>$cache2</span>->keyword2 = <span>array</span>("something here", 600<span>); __c()</span>->keyword3 = <span>array</span>("array|object", 3600*24<span>); </span><span>//</span><span> How to Read?</span> <span>$data</span> = <span>$cache1</span>->get("keyword1"<span>); </span><span>$data</span> = <span>$cache2</span>-><span>keyword2; </span><span>$data</span> = __c()-><span>keyword3; </span><span>$data</span> = __c()->get("keyword4"<span>); </span><span>//</span><span> Free to Travel between any caching methods</span> <span>$cache1</span> = phpFastCache("files"<span>); </span><span>$cache1</span>->set("keyword1", <span>$value</span>, <span>$time</span><span>); </span><span>$cache1</span>->memcache->set("keyword1", <span>$value</span>, <span>$time</span><span>); </span><span>$cache1</span>->apc->set("whatever", <span>$value</span>, 300<span>); </span><span>$cache2</span> = __c("apc"<span>); </span><span>$cache2</span>->keyword1 = <span>array</span>("so cool", 300<span>); </span><span>$cache2</span>->files->keyword1 = <span>array</span>("Oh yeah!", 600<span>); </span><span>$data</span> = __c("memcache")->get("keyword1"<span>); </span><span>$data</span> = __c("files")->get("keyword2"<span>); </span><span>$data</span> = __c()-><span>keyword3; </span><span>//</span><span> Multiple ?
