Great work giving us the nuts and bolts of PHP in C. I appreciate the hard work that obviously went into it

Given the devil is in the detail, I'd appreciate pausing at the end of slides for a bit longer, so we can catch up, before going on to the next slide.

Interesting but not very practical.

Great talk. Always good to learn more about the language and how it all works 'under the hood'. Found the VLD illustrations to be of much help and a nice range of examples were covered to give a thorough understanding. Would be good to get some more information on performance factors not directly linked to tokens (e.g. 'hello' and "hello" compiles the same opcodes BUT time is lost checking "hello" for variables. Would be good to get some examples where the opcodes might be the same but the steps to determine this may still require different amounts of overhead - if that makes sense/is written correctly...)

Very intellectual talk, however it was hard for me to see what i could take away from the talk

A really engaging and clear presentation of the underlying processes that occur during PHP execution. I really enjoyed this. Thanks Davey!

Davey was a very engaging and entertaining talker, and despite the fact that he was delving into some complex concepts, it was easy to follow and rather satisfying. Almost made me want to develop in C again. Almost.

Great analysis of generated opcode. You made a great argument against focussing too much on micro-optimisations. However, i felt the point could have been made in two or three sentences and it would have been more beneficial to go more into the remaining parts of the process to get a complete picture.
