A never-returning function must not return¶
Description¶
When using the never
keyword, the function shall not use the return
keyword. never
means that the function will not return, but rather die
, throw an exception, or trigger an error.
Also note that never
cannot be used in a union or intersection type.
This error message applies to functions, closures and arrow functions. In PHP 8.4, a separate message applies to methods.
Example¶
<?php
function foo() : never {
return true;
}
?>
Solutions¶
Remove the
return
keyword in the body of the function.Change the
never
return type to another type.
