Well explained, great technical content, and in-depth (as promised!)

As always, Derick gives a detailed talk about internal PHP things. As always, it's accessible enough to be understandable, but enough to make your head spin with complexity.

My favourite talk of the entire day loved the examples what php does behind the scenes

A fascinating insight into the steps that the PHP interpreter goes through and what it is actually producing opcode wise. Derek had some useful reminders to be more careful with branching code and that code coverage lies!

A fascinating insight into what's happening behind the scenes of PHP. Really well presented and very enjoyable.

I really enjoyed this. I like the technical talks more anyway, but have never really looked into how PHP parses and executes code in depth, and Derick provided a great insight into this while still keeping it easy enough to follow along.

Really good talk about the internals of PHP and how your source code gets converted to bytecode.
It was mentioned that things like opcache could optimise some of the resulting bytecode, but what I would like to know in a future talk is as a PHP developer, is how can I take this new knowledge and use it to make my code more efficient. I think this final step was missing.

Excellent talk, good to see the guts of PHP, (took me right back to my lex and yacc classes at uni :) )

The talk was crazy and intriguing - i loved it. Learning about how PHP works internally was inspiring, along with tokeniser, parsing and AST. As expected the talk was delivered confidently and precisely with excellent examples, Derick passion for this subject really shone through.

Interesting to hear how debuggers hook into the abstract syntax tree, and the problems associated with branch code coverage.

The immersion within the PHP internals and the jumps were really interesting, now I feel to understand PHP better thanks to Derick.
One tip would be to make some small pauses or more relaxed moments, since it's highly technical requires total attention, I know its hard to do that due the amount of content, but would be good to have some breaks, other than that everything was really good!

These complex technical talks always attract me but in some cases they are hard to follow. That wasn't the case with Derick's talk. It was really well presented with well laid out slides to make the complex content of the talk accessible. Great to see more of the internal workings of PHP.

I thought that I will be lost in first 5 minutes, but no. The content was well prepared and explained very nicely. I learned a lot from it, about tokenizer and how the php is translated into opcode.

Watching Derick is always enjoyable. Although this was very low level, it gave me enough to walk away from to look at books to learn from this talk further. Slides were clear and highlighted to give ease of following around.

If you want to get an understanding of PHP under the hood, then I suggest you watch out for this talk...

Dereks a great speaker, every talk I've been to by him has been well presented and interesting, this one didn't fall short of expectations, the topic was quite heavy and you had to think constantly during the talk on what was happening on screen, but this is good as it shows genuine engagement.

Topic gave a good insight to the internal workings, found it strange at first the way some loops are processed (jumping to the end then to the start if condition not met) but now makes sense

Thanks for the insight!
