May 13, 2024 - CMSes and frameworks such as Symfony, Drupal, and Laravel saw huge performance improvements going from PHP 8.2 to PHP 8.3 in Kinsta's PHP benchmarking, so I hope Debian will offer PHP 8.3 by default before too long.

r/PHPhelp on Reddit: What Do You Think About PHP 8.4's JIT Feature?
September 3, 2024 -

Hey PHP devs,
I’ve been experimenting with PHP 8.4, and I’m curious to hear your thoughts on the new JIT (Just-In-Time) compilation. It seems like it could be a real performance booster, especially for CPU-heavy tasks.

I’ve noticed some speed improvements in my side projects, but I’m wondering if anyone else has seen similar results. Do you think it’s going to change how we optimize our PHP apps, or is it more of a niche feature?

Would love to hear your experiences!

r/PHPhelp on Reddit: Any performance difference from upgrading from PHP 7.4 to PHP 8.2
January 20, 2023 -

Hi all, currently I have PHP 7.4.33 installed on my VPS server, and the server itself are very slow but had 1GB of RAM,

I'm kinda worried about the performance of my WP website on it, so I need performance improvement if possible on it.

r/PHP on Reddit: PHP 8.4 at least
August 13, 2024 - Let's say you'd start a new project ... choose PHP 8.2 or 8.3 — right? That's the angle I'm approaching from. There was another comment in this thread from a package maintainer that still supports 5.x and 7.x. I wonder why? The old versions of the package are still available. Let's say you're running a legacy project stuck on 5.x — there's no budget to update it, management has agreed with the potential security risks and performance penalties ...

I'm new to this and this is kind of a silly question but I am curious? What's the benefit of using 8.2 or 8.3 even though newer 8.5 has come out? and Do I have to keep changing my PHP version for my projects as newer version roll out?

r/PHP on Reddit: Just deployed our update from 7.4 to 8.3 - did it go smooth for you?
August 29, 2024 -

Was a long time coming, one of our applications is totally bespoke and we'v been leaving the update way too long owing time etc...

Good golly i'm never going to be sloppy and not declare variables or array indexes every again. I think i changed about 300 files lest the warning logs go into the GBs. Luckily phpcompatibility didn't find much in the way of breaking changes an array implode params the wrong way here or there.

Tests passed, working on test environments, regression testing done for good measure and i'v just deployed to live, yet there is still that feeling of unease on such a bit set of changes.

Did any of you guys face any challenges hoping versions? I want horror so i can sleep easier.

August 28, 2025 - The close of 2024 is near, and that also means a new version of PHP is about to be released: 8.4! There has already been some discussion regarding the latest features and modifications affecting developers, for example on either stitcher.io or php.watch. We wrote this post with a totally different angle, highlighting the performance, debugging, and operations-related changes in PHP 8.4 that are usually less publicized.

Catching up with PHP, from 5 to 8 : r/PHP
February 12, 2024 - Probably the most significant changes since PHP 5 are the improvements to type handling (strict types, scalar types, nullable types, return and parameter types, union types) and the error handling changes (while not 100% there, the vast majority of PHP now uses exceptions and thrown errors by default) JIT is, in my opinion, something most developers should not concern themselves with (particularly in its current state). I would say it's something you use when you've performed all other optimizations you can and want to eek out every last ounce of performance. There are some significant changes being made to it in 8.4 (the next PHP version that won't be released until Nov/Dec 2024)
