Cooperative multitasking with generators
summary
Shows how PHP generators (added in PHP 5.5) let functions yield pauses and resumes execution so a file reader holds only one line in memory and a bubble-sort can emit intermediate steps; builds a cooperative multitasker in about 64 lines of code that runs tasks interleaved in one thread (asynchronous not parallel). Demonstrates use of amp, react PHP and recoil, and an actual site (pre-process dot IO) using generators with promises to run a non-blocking HTTP server in production.
