This example describes the PHP cache integration library phpFastCache usage. Share it with you for your reference. The specific analysis is as follows:

PhpFastCache is an open-source PHP cache library that provides only one simple PHP file and can be easily integrated into existing projects. It supports multiple caching methods, including apc, memcache, memcached, wincache, files, pdo and mpdo. You can use a simple API to define the cache validity period.

The Code is as follows:

<? 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 ();

// 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

The Code is as follows:

<? 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 cils next time
$ Cache-> set ("identity_keyword", $ results, 24x3600 );
}

Foreach ($ results as $ video ){
// Output Your Contents HERE
}

Full page Cache

The Code is as follows:

<? 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;

Pendant Cache

The Code is as follows:

<? 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;

Multiple caches at the same time

The Code is as follows:

<? 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 ("127.0.0.1", 11211,100), array ("128.5.1.3 ));
$ 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 ("Also 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 "));
