Question

Is there a way to fetch and print, all the data stored in apc’s storage?

I need to do so for testing and debugging purposes.

I know I can retrieve a specific data by doing apc_fetch(id), but I don’t know any way to retrieve all the data by passing (as an example) a *

Yes, you can get this with APCIterator. This allows you to loop through all the items stored with APC.

$iter = new APCIterator('user');
foreach ($iter as $item) {
    echo $item['key'] . ': ' . $item['value'];
}
