php - Sharing complex objects across controller methods Laravel 5.1 -

given following scenario:

controller@method_a spawns process (symfony process object) asynchronously, controller@method_b needs interact process

how implement sharing process object?

things i've went over:

controller properties don't persist, each request controller gets reinstantiated
session can't store complex objects, , serialization take soul of it
database can't store complex objects either

edit:

to serialization issue:

    $process = new process("dir");     $process->start();     $x = serialize($process);     dd($x);

if remove $process->start(), not fire serialization of 'closure' not allowed. can't handle process that's not started.

i guess option here serialize object , persist somewhere (db, session, file). in next request, pull , unserialize.
