Partial Function Application is coming in PHP 8.6

Read Original

This article details the upcoming Partial Function Application feature in PHP 8.6. It explains how PFA allows developers to create pre-configured callables by using '?' and '...' placeholders for arguments, reducing boilerplate code in callbacks and making them more readable. It includes examples, patterns, and discusses integration with named arguments, variadics, and the pipe operator.
