PHP extended classes Recently, I discovered that Datetime::createFromImmutable is now returning a static type : it returns an object of the type that called the method. This is only useful when the class has been extended by another class. This means that the Datetime class is extended enough for PHP to acknowledge it and adapts […]

14 PHP arguments that are not enough used PHP has a few thousands functions under its belt, and there are even more arguments. And just like for functions, some of those arguments are not often used, while they provide a useful extension to the original behavior of the function. To catchup with them, here are […]

Removing a value in an array, six methods Removing one value is a classic task, and it is quite natural to discover multiple ways to do so.

Semantic typing Semantic typing is an old practice, where the name of the parameter would also tell what its type is. It is typing, because a $string is supposed to be typed, and it is semantic, because only the human reader is actually using the meaning : PHP doesn’t really care. The interesting part is […]

Let’s make PHP more abstract abstract is a conception keyword. It is decided during the conception phase that some classes and some methods uses the abstract keyword. Later, that keyword might disappear as needed, yet abstract never appears sponteanously. Nobody decides abstraction late in the coding phase. That seems to be a lack of practise […]

Adding the last types to PHP code Adding types to PHP code is a staple of any PHP code refactoring. With a code base crawling towards 10 years and over 2000 classes, Exakat is quite a consistent piece of software, with a lot of parameters, methods and properties. Covering everything with types was long, and, […]
