With PHP that is not strictly true. I've found versions in Debian which
timeout on script execution duration and halt the helper. Leading to
your "logs have a size of 0byte." state.
I'm getting a bit fuzzy nowdays since I dropped PHP myself as a helper
language some months back. But IIRC there was at least on version where
if I/O happened frequently enough it kept running for longer. If you are
lucky you may have that version of PHP.

No requests *sent* to the helper. Which is what we are looking for.
Indicating that the aforementioned timeout is probably the cause of
this.
If your helper is not doing anything beyond loading the SRC IP in
database and sending some associated username back to Squid you could
try the SQL_session external ACL helper bundled with 3.3 and later.
