IMPORTANT QUESTIONS
HOW CAN WE MOVE TO PHP 7?
▸ Review PHP 7's changelog
▸ are we still using deprecated functions?
▸ are we using PHP extensions?
▸ do we depend on 3rd party packages?
THE BEST WAY TO LEARN…
I PRESENTED ON PHP 7
▸ Required me to do the research
▸ Needed to engage with PHP core developers
▸ Played with the code base
▸ Simulated small challenges
▸ Reviewed the results
▸ BONUS: I could speak at meetups!!!
PRESENTING ON A SUBJECT IS THE BEST WAY TO BECOME AN EXPERT ON THAT SUBJECT.
