问题 I have the following setup: I parse an api response that has a structure similar to this (I oversimplify a bit): { orders: [ { // some data customers: [ { // some data addresses: [ { id: 436456445 // some data }, // Other addresses ] } ] }, { customers: [ { addresses: [ { id: 436456445 // some data } ] } ] } ] } Note that a specific address appears twice in the response (same id). I deep travel (hope is the right translation) the structure and make entities. All goes well until the save part

I tried adding a choicetype with multiple choices to the form but it didn't work. Can you guys help me ? Entity Agent: <?php /** * @ORM\Entity *

问题 I want to use Argon2i for my Symfony 4 encoder as I've seen multiple articles about how it's supposedly better than bcrypt or pbkdf2. Unfortunately I don't really know what values to use for the memory_cost, time_cost or threads on my system.
