1.2.747. Named Argument And Variadic

Variadic argument must be the last in the list of arguments. Since PHP 8.1, it is possible to use named arguments after a variadic argument.

<?php
  // named arguments may be after the variadic
  foo(...$a, a: 1);

  // positional arguments MUST be before the variadic
  foo(...$a,  1);

  // Normal way
  foo( 1, ...$a);
?>

1.2.747.1. Suggestions

• Always put the variadic at the end of the argument list
