I'm using APC to cache user variables (with the apc_store/apc_fetch commands). I've also enabled APC for the CLI with the option "apc.enable_cli = 1". However, the CLI version of PHP seems to access a different APC cache from the version used by Apache.
Is it possible to configure APC to use the same cache for both CLI and web invocations?
Not possible.. The only way to accomplish something like what your asking is to use something like memcacheD. Or run what you need to run through your webserver. What's running CLI that you cannot run via a web script with a cronjob?
