This function can not be called statically.

Example

Example 36-1. Usage

<?php
require_once "Cache/Lite.php";

$options = array(
    'cacheDir' => '/tmp/',
    'lifeTime' => 7200,
    'pearErrorMode' => CACHE_LITE_ERROR_DIE
);
$cache = new Cache_Lite($options);

$cache->remove('id_of_the_page');

if ($data = $cache->get('id_of_the_page')) {

    // Cache hit !
    // [IMPOSSIBLE !]

} else { 
    
    // No valid cache found (you have to make and save the page)
    $data = '<html><head><title>test</title></head><body><p>this is a test</p></body></html>';
    $cache->save($data);
    
}

?>

This is a dummy example because the cache is destroyed at the beginning of the script ! So the first case of the if statement is impossible.
