return.never

Code example

<?php declare(strict_types = 1);

function terminate(): never
{
	return;
}

Why is it reported?

The function or method has a never return type, which means it must not return at all. A function declared as never is expected to always throw an exception, call exit()/die(), or enter an infinite loop. Having a return statement in such a function contradicts the never return type declaration.

How to fix it

Either remove the return statement and ensure the function never returns:

 <?php declare(strict_types = 1);

 function terminate(): never
 {
-	return;
+	exit(1);
 }

Or change the return type if the function is meant to return:

 <?php declare(strict_types = 1);

-function terminate(): never
+function terminate(): void
 {
 	return;
 }
