I explore various questions pertaining to a medley of topics. Initially the talk focuses on some undocumented fun to be had with identifiers. Attention next shifts to PHP’s comma operator and considers whether it even merits that designation. The main topic, which follows, derives from an example of some very questionable PHP logic. To avoid making a hasty, superficial judgment will entail discovering the hidden story behind PHP’s truth values. Particularly fascinating is the influence of other languages on their development and meaning. This segment also peers into PHP’s internal workings in a friendly fashion for non-C programmers. Novices as well as senior developers are all welcome; there’s plenty of code for everyone! Come learn about what surprises await you.
