From: php at bouchery dot com
Operating system: Irrelevant
PHP version: Irrelevant
Package: Documentation problem
Bug Type: Documentation Problem
Bug description:Undocumented Backward Compatibility Break from 7.0 to 7.1
Description:
------------
---
From manual page: http://www.php.net/migration71.incompatible
---
When "return" without value in a function using return type into PHP
7.0, this will not generate fatale if "return" is not executed.
When migrating to PHP 7.1, it will generate a compilation error "Fatal
error: A function with return type must return a value" even if "return"
is not executed.
Test script:
---------------
<?php
function foo(): int {
if (false) {
return;
}
}
?>
Replace the "false" condition by what you want, never or rarely called.
