The Case Of The Insensitive Filesystem There is a special kind of bug that only exists between your laptop and the production server. It compiles, it tests, it ships, and then it 500s. Somewhere along the way, User.php became user.php, and one of the two machines had an opinion about it. PHP has no opinion. […]

When PHP Meet Unicode: A Tour of Identifiers Beyond ASCII Every year, like clockwork, someone rediscovers that a day is not reliably 86400 seconds long, gets righteously indignant about daylight change on Hacker News, and two hundred comments later the whole internet has relearned a lesson it relearns every March and October.

Hidden Traps with Chained Assignments If you’ve been writing PHP for a while, you’ve almost certainly written a few chained assignments yourself. It’s that neat, concise trick where you initialize multiple variables or properties on a single line: It looks clean. It feels efficient. It’s the kind of line that makes you feel, for one […]
