Little implementation of a cache system in PHP
The class oz\Cache requires a little configuration using the oz\CacheConfiguration class. The params are:
- folder: The path where the cache files are going to be stored.
- extension: The extension the files are going to have.
- hashMethod: The names of the files are encoded to be unique. The hash method can be sha1, md5... and all methods that the function hash of PHP can use.
So, you can have multiple cache directories. The oz\CacheConfiguration class provides a simple default configuration:
- folder: /.cache
- extension: .cache
- hashMethod: sha1
After configuring the cache, it can be used as an array as it implements the ArrayAccess interface:
use oz\CacheConfiguration;
use oz\Cache;
$cacheConfiguration = CacheConfiguration::getDefaultConfiguration();
$cache = new Cache($cacheConfiguration);$cache['foo_text'] = 'This is stored as text';
$cache['foo_number'] = 3000;
$cache['foo_bool'] = true;
$cache['foo_object'] = new \stdClass();
$cache['foo_array'] = array(
'foo_1' => 'You',
'foo_2' => 'can',
'foo_3' => 'store',
'foo_4' => 'the',
'foo_5' => 'basic',
'foo_6' => 'data',
'foo_7' => 'types'
);isset($cache['foo_text']); # True
isset($cache['foo_txt']); # Falseecho $cache['foo_number']; # 3000
echo $cache['foo_text']; # 'This is stored as text'unset($cache['foo_text']);
echo $cache['foo_text']; # Notice: ... doesn't existHave fun ;)
