I got a lot of positive feedback on my talk about queryable encryption with Doctrine at #Symfony_Live Paris. So I’m presenting it again in English for Symfony Online. I’ll cover cryptography best practices and the inner workings of the Doctrine ORM.

In the Symfony configuration, you can use `when@<env>` to set a different configuration value depending on the environment. What you're suggesting is pretty much the same thing. symfony.com/doc/current/...

“It would be fully typed and other stuff that belongs to the property through attributes. Everything would be collocated to the property. I don't think it's out of the World equation of having properties in Eloquent” — Nuno Maduro

Just when we thought the #Symfony Dependency Injection component was feature complete, we've opened a new chapter with the introduction of resource definitions. Classes that are not service can be tagged according to the interfaces or attributes they use, which can then be injected into services.

A reminder for maintainers of #PHP libraries: adding a parameter to a method of an interface causes a fatal error in all the classes that implement it. It's a BC break that should be prohibed in a minor version. In Symfony, we add the parameter virtually using phpdoc, and read it using func_get_arg.

$PHP code: /** * @param int $nbToken * * @psalm-param int<1, max> $nbToken */ public function mark(string $place /* , int $nbToken = 1 */): void { $nbToken = 1 < \func_num_args() ? func_get_arg(1) : 1; } Source: https://github.com/symfony/symfony/blob/01c26aa928ecc5dc42ce90268299c190c6b712ed/src/Symfony/Component/Workflow/Marking.php#L39$

Deprecating the implicitly nullable parameter in #PHP 8.4 had a huge cost for the maintainers. Even if there are solutions to automate the fixes, that breaks almost all old code with very low value for developers. My article about fixing this is by far the most popular I have ever published.

Article about fixing the deprecating got 27k views.

I couldn't resist doing some perf optimization on a very algorithmic lib. It's nice to be able to validate the gain with phpbench. - Use regex - String manipulation instead of array of chars - Memoize results

Best practices for data modeling: - The workload determines the optimal grouping of objects into collections - what is used together in the application is stored together in the database - MongoDB let you develop and deploy quickly and also evolve your application and schema quickly
