Today is good day to learn that in #PHP, if the documentation says
function foo expects arguments A and B and if B is not defined it'll be like passing "null"
that does NOT mean that
foo(A) and foo(A, null)
will produce the same results.
Actually, it might be the case that foo(A, null) throws an exception and dies.
Keeping life exciting, PHP is.

I wish PHP 9.0 had a feature called "Flag".
No more bitwise operators, just fluent flag declaration. I'll prefer that rather than adding numbers and then wondering what is "8 | 16".

@jetbrains is sunsetting the feature I use every day! Code-with-me will be removed, the way to do pair programming for remote teams.
https://blog.jetbrains.com/platform/2026/03/sunsetting-code-with-me/
Why does jetbrains keep pushing me away? First forcing their AI, now end of code-with-me. I need to look for an alternative replacement. #php #pairprogramming #remote #ide

I was ready to create an issue on @phpunit because of a strange behavior that I dug for a few hours...
While writing the description and explaining the details, I found that the issue was my own code...
Take the time to step back and explain to someone, an issue or an object on your desk. Most of the time a solution will come !!

Wrote a simple #PHP script that runs once an hour.
Against a database with a couple of hundred records.
On a VPS that manages to hold its own against the bots while hosting both a fedi instance and a code forge.
But still it irks that it’s doing N+1 selects 😞 (actually, more like 3N+1 even)

Using loadMissing() to avoid duplicate queries? If the relationship was previously loaded with a filter, you might silently get incomplete data. Here's when the extra query is actually worth it. #php #laravel https://masteringlaravel.io/daily/2026-03-16-when-loadmissing-works-against-you

flow-php/parquet just got another significant performance boost 🤯
Our next goal is to create an php extension that would let us use Apache Arrow C++ parquet implementation and make parquet in #PHP even faster!

I miss PHP Internals News podcast.
I hope the PHP Foundation introduces Elizabeth Barron through official channels instead of random streams shilling AI slop, copyright infringement, and JetBrains subscriptions.
