Named arguments is a new feature introduced in PHP 8.0, which allows you to pass arguments to a function or method by specifying the parameter name along with the value. This feature provides developers with more flexibility and improves code readability.

Traditionally, in PHP, function parameters are passed by position, which means the order in which arguments are passed to a function must match the order of the parameters in the function signature. In contrast, named arguments allow you to specify which parameter you are passing the argument to, without being constrained by the order.
