How to fix "undefined index" globally in PHP8.x?

Hello,

I have to migrate some websites that were created under PHP 5.x to PHP 8.x
Most of the time, the frontend works right away or only needs minor changes.

The administration is driving me nuts though.
First off, it was custom made 10+ years ago and not the very elegant of code to begin with. But it works fine up to PHP 7.x

With PHP8 I get tons of "undefined index" errors. This happens, because of checking variables that do not exist (are not set) yet. It never was a problem before, but PHP8 is very strict about it.

For instance:

if($_SESSION['order'] == "" AND $_GET['order'] == "")
{
$_SESSION['order'] = $default_order;
}

immediately throws an error if neither Session nor Get are set.
Please don't get mad about this very code, I know it's not good, it's just to demonstrate.

The problem is, that there are a lot of variables that CAN be set but don't have to be, depending on the actual area.

It is not feasible to start by setting each and every variable at the top, there are way to many and some of them are dynamically set too.
It is also not feasible to insert if isset() into every statement.

Sure, I can supress errors, but I'd rather fix this for good.
Is there a way to tell PHP8 to assume those variables are set but empty until I actually give them a value?

Ecotone Framework - New website and Enterprise version

Hey,

Some of you may already know me, I am author of Ecotone Framework and I am posting PHP related articles about Message-Driven Systems, DDD and Architecture in general.
And today I would like to share two big changes to Ecotone Framework, that I've been working on for over year.

I know that due to volume of features, Ecotone's documentation may require time to fully go over different functionalities and reasoning behind them.
And of course not everyone have time to do so, or simply one could feel that all the tools Ecotone provides he already use therefore there is no point in testing it out.
Therefore to make it clear what Ecotone is about, what it provides, without requiring bigger time investment, Ecotone comes now with new website at: https://ecotone.tech

The aim of new website is to provide as much as possible details to get general feeling, without the need to install or run the framework itself.
New website provides denoscription of features, detailed code examples, and steps on how to get started.
I hope this will be helpful in giving more details on Ecotone in quick and easy way, and will help to make the decision whatever it can help your project.

The other big thing which Ecotone brings to the table, is Enterprise version.
Ecotone Enterprise includes more custom advanced features, additional integrations, and ability to optimizatize the system usage.
The aim of Enterprise is to get more support for Ecotone, in order to build even more tooling around it.
To get more details about some of the core Enterprise features, you take a look on today's article: https://blog.ecotone.tech/ecotone-enterprise-kafka-distributed-bus-dynamic-channels-and-more-2

thank you,
cheers :)

Filament Json Column - Releasing v1.6.1

Hey everyone!
If you've used FilamentPHP, you might have heard about Filament Json Column, as the plugin is now getting closer to a 100K downloads.
I've made a new release, with a whole rewritten code base for better maintainability (Ok, it's not that big but still). I've added the following features:

Validation: If the JSON is invalid, the user can't switch tabs or submit. An error message is displayed on submission. Error message can be customized and supports \`\_\_()\`
Editor mode customization (code, text, tree, etc...)

Please see the updated docs on the link above. Planning to add an Infolist component, and some Alpine automated testing. If you have suggestions, or want to contribute, please don't hesitate to send me a message here or a pull request on GitHub.
Have a great day!

Is it possible to embed a CRUD within another CRUD using EasyAdmin?

I am working on a Symfony 7 project that uses EasyAdmin 4 for the back-office. I have a Formation entity that can have multiple Prices.

In the creation and editing views of Formation, I would like to add a "Prices" tab containing an index and a CRUD EasyAdmin to manage (create and modify) the prices associated with the formation. How can I achieve this?

I have looked for tutorials but haven't found anything similar. I also tried to figure it out on my own, but it didn't lead to any conclusive results.

here is an example of what i'm trying to do

is there in-memory search engine for PHP?

Does php have an in-memory search library?
like https://duckdb.org? or lucene?

I'm aware of elasticsearch and solr and redis search, but was hoping for something simpler.

Good exception patterns to follow?

I recently saw that a colleague had defined a method in his new exception class called asHttpResponse() that sends back an instance of Psr\\Http\\Message\\ResponseInterface.

That got me thinking: Are there other patterns related to exceptions that are simple, easy to follow and helpful? I know woefully little about this topic.

Full disclosure: If I really like what you have to say, I'm likely to steal it for a lightning talk :-)
