Data processing in #PHP is still in it's early stages. Don't believe me? Look at your system and tell me how it's handling imports/exports.
Is it perhaps hand written importer/exporter?
Any chance it's using file_get_contents?
What stops you from using a Data Frame?

flow-php/postgresql received Client::explain() : Plan feature
This means that we can now programmatically extract and analyze postgresql query execution plan!

flow-php/pg-query quickly escalated from "I just want to parse sql to AST" into "why not build a proper query builder?" 😅
So there is, #PHP Query Builder for #PostgreSQL inspired by JOOQ
(API will change, this is just PoC)

Flow #PHP library for parsing SQL flow-php/pg-query just got significantly better!
Now it can not only turn query into AST but also convert AST to nicely formatted string!

Another addition to Flow, auto generated Table of Contents to easier get to relevant sections of documentation 😁

I just upgraded Flow #PHP Playground.
Now it opens preview of predefined/uploaded files in tabs.
I also added some colors to the output to make it more readable.

I'm very excited about what I'm going to share now!
Flow #PHP just received a fully interactive playground allowing to build and execute ETL pipelines directly in the browser!! 🤯

1/8 I have been recently playing with the idea of creating an interactive playground for Flow #PHP where the ETL pipeline can be executed directly in the browser.
Today I managed to put together the first working version!

Flow #PHP documentation just got significantly better 🤩
From now on, each example can also have multiple options - third nesting level.

Flow #PHP can now be run on Windows! But not through WSL, pure Windows. The main blocker was the flow-php/filesystem library. I managed to turn the Path class into a facade that detects the OS and uses dedicated Windows or Unix Path implementation under the hood.

- we now have AST Traverser with Visitors detecting dangerous functions/classes usage
- we have linter used on the snipped
Both, Parser and Linter are generating Violations that are later mapped to a code editor

@Tailscale VPN joined sponsors of Flow #PHP 💪
Tailscale is one of the easiest to use but also extremely flexible VPN service providers 🚀
I think it's time to reveal what we are trying to build 😊

2/6 Parquet optimization:
Due to heavy refactoring of the Parquet library for reading/writing, we managed to improve the overall library performance by almost 99% (I/O / Mem).

1/3 Flow #PHP - Doctrine Dbal Bulk is a small, standalone library (can be used without Data Frame) that helps with Dbal bulk operations.
Now we can manually pass column types, giving the user not only more control but also reduce resources consumption on types detection.

I'm not using LLMs to solve my coding problems or to code (they can't do it). I'm using them to see more potential solutions to my problem before I make a decision on which one is the best. This is a massive time-saver and productivity boost 🚀 for just $20/month (for now).
