PEAR::Cache can cache more than just output. It also can cache the results of a function call: call('myfunction'); $result = $fcache->call('anotherfunction', 'parameter'); /* Caching the result of a static method in a class */ $result = $fcache->call('myclass::mymethod', 'parameter'); /* Caching the results of method being called against a specific instance. In this case, calling the method $mymethod of the $bar object */ $result = $fcache->call('bar->mymethod'); ?>]]>
