%s%s%s(): Return value must be of type %s, %s returned¶
Description¶
This error appears when calling a method with a return value, but without an explicit return statement. This means that when the method reachs its end, eventually, it will end without a returned value. Yet, the method signature declares that it will return a specific type.
A different error message is returned when an empty return
statement is used.
Example¶
<?php
function foo() : int {}
?>
Literal Examples¶
foo(): Return value must be of type int, none returned
Solutions¶
Add a return call, with a valid value.
Remove the return type.
Add a null to the return type, and return it (void is not possible with another type).
