This talk discusses various issues of low-level PHP performance, such as: When is it more efficient to use arrays or objects? What causes catastrophic garbage collection? Does adding type annotations make PHP faster or slower?
I will answer these types of question with a (shallow) dive into PHP internals, touching on various topics like value representation, bytecode optimization and GC.
