Watch Chris Holland's International PHP Conference session

A Case for Generics in PHP

JAX Editorial Team

Avoiding surprise-ducks at run-time… PHP 7 has brought us improved support for types, making us less reliant upon annotations. Yet we still can’t say function foo() : User[] What makes an array of users so special? What if we’d like to return a HashMap of a given key & value? We’ll explore use cases for defining composite objects and leveraging generics to avoid repeating ourselves.

In 2016, Ben Scholzen and Rasmus Schultz drafted an RFC for “Generics in PHP”. Having worked with these constructs in Java and C# in past lives, Chris Holland can offer several examples of practical use-cases for them, and help bolster a case for their adoption in PHP. In the end, we should arrive at how they would nicely complement the most recent enhancements to PHP 7’s type system.
