1. The document discusses asynchronous programming in PHP using ReactPHP and compares it to Node.js. It covers non-blocking I/O, event loops, and the reactor pattern. 2. Examples of when to use ReactPHP/Node.js include for chat applications, APIs, queued input, data streaming, proxies, and monitoring. Relational databases and CPU-intensive tasks are given as examples of when not to use them. 3. Differences between Node.js and ReactPHP mentioned include Node.js having more packages/libraries while PHP is more compatible with existing backend code. Node.js is also described as more mature while PHP has better OOP support.

"The select and poll system calls allow a
set of file descriptors to be monitored for
a change of state, [...] by using files to
trigger and listen to events, the loop will
block if there are no events ready."](https://image.slidesharecdn.com/phpassncronocomreactphp-220105194242/85/Php-assincrono-com_react_php-18-320.jpg)
