PHP has been around since the beginning of the Web. It has shaped and influenced many of the sites and web technologies we use every day. The SQL LIMIT clause came out of the PHP project, for example. Now, getting close to its 25th birthday, can it still make an impact?

Looking forward to trying out phan.

Great talk about historical PHP and how it's moving forward. I love the sound of the refinements and performance improvements in PHP 7.2 and Phan is going to be fun to experiment with.

David Carr at 12:03 on 30 Sep 2017

Really great talk, interesting background and humour and great details

Kat Zien at 13:34 on 30 Sep 2017

Such a great talk. Really really informative run through what's coming out in 7.2 and beyond, and I LOVED the easy to follow examples of opcode caching optimisations. Enjoyed the history intro too. Thanks for all the graphs and stats on CO2 savings - that gives us all a great argument to go back with to our business owners and badger them about upgrading to 7! :)

Very well prepared and structured talk, and delivered without a glitch!

A great opening keynote from Rasmus. I learnt a lot about optimisations in upcoming PHP releases and static analysis with Phan.

Lots of useful data. Enjoyable insight into the direction on core.

Fascinating overview as ever from Rasmus on the history of PHP and some of its more exciting modern features, proving the language carries on getting better and better.

Screw this. return 4.


Really enjoyable talk with a great mix of humour and technical details.

A great opening keynote.
I really liked how simplified Rasmus's explanations were for some complicated areas like JIT. Lot's of things to think about and to look forward to for 7.2, 7.3 and beyond.

Great insight into the benefits of the latest PHP version delivered, very insightful.

Really interesting, relatively in depth but easy to understand concepts exposed throughout the talk. It really makes a point, and point out that legacy code will definitely benefit from the coming improvements.

Great content, great execution, all perfect for me!

Chris Hughes at 09:41 on 1 Oct 2017

Great opening keynote, enjoyable and engaging insight into the clear benefits of PHP 7.x

Dave Liddament at 11:11 on 1 Oct 2017

Great talk. Really interested to learn about the early days and how PHP came about.

Interesting to learn about PHP7.2 and beyond, especially the optimisations.

Also definitely going to look at phan.

Katy Ereira at 13:26 on 1 Oct 2017

It's really nice to see where PHP has come from and what's happening next!

Great opening talk, really set the tone and mood for the rest of the conference, but also had nice detail in it too!

Claire Gurman at 16:00 on 1 Oct 2017

Really good informative talk. Looking forward to trying it all out.

Chris Emerson at 16:33 on 1 Oct 2017

Enjoyable and informative talk about both the history of PHP and where we are now, including some of the great things coming too

Scott Dutton at 17:53 on 1 Oct 2017

Really good to see early versions of php and a nice reminder of how far php has progressed.

It's great to see that php was the first major programming language to have security features right in its core.

Would be nice for everyone to upgrade to php7

John Cleary at 18:04 on 1 Oct 2017

Lots if interesting stuff, even for a non PHP Developer ;) More pictures of retro computers pls.

Fabiana Asara at 19:24 on 1 Oct 2017

It was my first Php conference and I have enjoyed every single word of your talk. Great humour and technical details way well explained.

Ben Plummer at 21:00 on 1 Oct 2017

Really applicable opening keynote covering the history of PHP and what's to come in the future, amongst other things. Can't think of anyone more appropriate to have given a talk of this content.

Mark Railton at 21:13 on 1 Oct 2017

Fantastic talk. 3rd time seeing Rasmus deliver this talk, but each time it's different, he keeps the talk updated for what's currently going on with PHP.

Good talk, a bit of interesting history and most importantly new features in PHP 7.2 and 7.3
Good to know that PHP is still improving.
Interesting info about Phan, JIT and Vespa.
Just one thing could be improved: There could be more about how we developers can help to improve PHP, and less how we developers write bad code.

Matt Brunt at 21:22 on 1 Oct 2017

While some complex topics such as Dead Code Elimination were covered, the style, pacing and slides made it very easy to grasp some of the new features in PHP 7.2 and even 7.3.

A great way to kick off the conference!

Alex Lungu at 23:25 on 1 Oct 2017

Great way to start this year's conference!

Phan looks like a great tool to try out

What better way to stay updated on new developments in PHP than to listen to Rasmus talking about it. Got some really good information about this talk on the new 7.2 and 7.3 optimizations as well as Vespa. Thanks!

Mike Lehan at 09:11 on 2 Oct 2017

Quality talk from the guy who started it all. Was most interested to have learned some of how PHP came about in the early days, but also interesting to see some new optimisations. I think a bit of extra info for those less familiar with how PHP core works would have been useful - i.e. how do these new features come about, who decides what goes where. That's just a request for the next one though!

Patrick Asare at 09:32 on 2 Oct 2017

Happy I got to see/hear this from Rasmuns himself. PHP has come a long way. Phan looks great as well.

Olubajo Bolaji at 09:34 on 2 Oct 2017

One of the best talk of the event

Great talk, good balance between information and humor. Really looking forward to give PHP 7.3 a try ;)

Iain Fogg at 07:40 on 3 Oct 2017

Exciting dive into PHP history and new development to improve PHP performance, also phan is now on my 'to try' list

AlwinD at 13:27 on 5 Oct 2017

Great insights in the upcoming PHP versions.

Erik Smit at 16:47 on 8 Oct 2017

Inspiring and fun to see Rasmus talk passionate about his PHP and the near future of it.
