Thanks @nicolasgrekas for fixing a use-after-free in parallel. I just released v1.2.12 github.com/krakjoe/parall…

@alexdaubois It's a hack, it fills the array, but it also allocates all elements in the packed array or hash map in one go, so no reallocations needed 🎉

@realFlowControl I wasn't aware that preallocating arrays in PHP was a thing, but it makes sense. array_fill() may be more useful than I actually thought! Thanks for sharing this 🙏

SplFixedArray uses ~60% less RAM than a regular array in #PHP. That's because regular ones are always (re)allocated with a power-of-2 capacity. 1025 elements? 2048 allocated! Fixed size. Integer keys only. No hash table overhead. Since 5.3. I almost never see it used, do you?

@alexdaubois See #L2649" target="_blank" rel="nofollow noopener">github.com/php/php-src/bl… for `array_fill()`

@alexdaubois Try running with `$size = 2_097_152` and memory overhead for the array is just ~6% (due to the ^2 realloc). If you want to avoid the reallocations, use `array_fill(0, $size, 0);` to "pre-allocate" a packed array, which makes it faster then SplFixedArray

@alexdaubois I did use those two in a template engine I wrote two decades ago ;-)

2 long forgotten functions of #PHP: compact() turns variable names into an associative array. extract() does the reverse. Named in PHP 4. Still works. Most devs forgot they exist. Where do you see this being used?

New year*, new parallel release: v1.2.11 just landed with stability fixes 🎉 github.com/krakjoe/parall… * right on time for the Chinese New Year 🔥🐴

@tideways Congrats on ten years 🎉

Ten years of Tideways! Thank you for being part of the journey. Tideways was born from a desire to improve. Benjamin saw PHP apps fail under load, not knowing why. This sparked the idea for a tool focused on profiling, monitoring, and exception tracking. tideways.com/profiler/blog/…

We are proud to count DataDog among our sponsors for ConFoo 2026. buff.ly/JnwfHPN

I’m heading to @confooca 2026 in Montréal 🇨🇦 in a few weeks, where I’ll be speaking about two things I care a lot about in the PHP world: observability and multithreading. Hit me up if you want to talk performance! 🚀 #ConFoo #PHP #Observability #Performance #Multithreading

@another_clue 👍

Using PHPT test files for integration tests in #PHP 👍/👎?

Your favourite PHP multithreading extension just got tougher. `ext-parallel` v1.2.9 fixes crashes caused by doing things you technically shouldn’t do 😉 Better stability, fewer segfaults. github.com/krakjoe/parall…

The 2026 State of Open Source Survey is live, and the #Zend team and I want to hear how you're using #PHP and other #OSS technologies. Your anonymous answers will be used to build two industry reports, available free next year: surveymonkey.com/r/FT3SWPL

@kotomin_m Get well soon

In February, you’ll get the chance to meet an amazing group of people in London 🇬🇧 at the @PHPUKConference 🎉 Grab your ticket at phpconference.co.uk/tickets (if you have not already) and hit me up, if you want to talk about #performance and #observability in #PHP

The #longhornphp 2025 tutorial day is underway! @alenaholligan is presenting on BDD, @realFlowControl is walking through building an observability extension with Rust, and @DaveLiddament is diving into building custom Rector rules.

@dianasoyster @LonghornPHP Yes, I'll be around for the rest of the conference

@realFlowControl @LonghornPHP Unfortunately I can’t make this one but will you still be around for the other days? I’d love to chat with you about it after ☺️

Thrilled to bring my workshop Observing PHP for Fun and Profit to @LonghornPHP this year! 🚀 We’ll peek under the hood of the PHP engine and even build our own extension in Rust. Come hack on internals with me 👉 longhornphp.com

Want to attend Longhorn PHP in person, but can't afford a ticket? Thanks to the PHP community, we have a few free tickets to give away to those who need it. We're just asking for a $20 refundable deposit. Register here: ti.to/longhorn-php/l…

We are excited to have @realFlowControl presenting a tutorial in addition to his keynote. We'll learn all about Observing PHP for Fun and Profit! Deep dive into the PHP engine internals and build a PHP extension to measure performance! Join us at longhornphp.com

Florian ft. the purple elephpant are up! #CakeFest

Looking forward to seeing everyone for #CakeFest next week! Don’t forget we will be streaming live on youtube.com/CakePHP 🍰 October 9-10 at 9:00 GMT+2 Thanks again to @passbolt - our DIAMOND sponsor! CakeFest.org
