#pulpCache

A simple Cache class

---

##Usage

###Initialization

To initialize a new Cache, simply create a new Instance of PulpCache

$cache = new pulpCache();

There are a few options you can add as an array:

cache_dir: Target directory for the cache (default ./cache)
config_file: Name of the Cache Configfile (defailt config.json)
expire_at: TimeStamp at which the Cache will be marked as old next (will be overwritten with each "save")
cache_name: Name of the Current cached file
ttl: Time to live (in Seconds). This will be used to set "expire_at" (current time + ttl). Default: 86500 (One Day)

#####Example <?php

require_once(dirname(__FILE)) . 'pulpcache/pulpCache.php');

$config = new array('cache_dir' => '/path/to/cache/dir',
					 'cache_name' => 'file_to_cache',
					 'ttl' => 3600
					);
$cache = new PulpCache($config);

###Caching

To actually cache Content, there are 3 methods you should use:

hasCache() : Returns true if there is cached content available
getCache(): Returns the cached Content
saveCache($content): Saves $content

#####Example

<?php

require_once(dirname(__FILE)) . 'pulpcache/pulpCache.php');

$config = new array('cache_dir' => '/path/to/cache/dir',
					 'cache_name' => 'file_to_cache',
					 'ttl' => 3600
					);
$cache = new PulpCache($config);

$content = "";

if(!$cache -> hasCache() ){
	
	...
	... Fill $content wicth Content
	...
	
	$cache->saveCache($content);
	
} else {
		$content = $cache -> getCache();
}

echo $content
