Previous Comments: ------------------------------------------------------------------------ [2019-03-21 22:35:10] requinix@php.net Duplicate of request #72589. ------------------------------------------------------------------------ [2019-03-21 06:07:26] xxalfa at gmail dot com That's right, with "foreach" and "return" it makes no sense. "require_once" returns a 0 or 1. Why does not "goto" do the same? Can I jump = 1, I can not jump = 0. ------------------------------------------------------------------------ [2019-03-21 03:18:46] requinix@php.net For the same reason you can't do it with a foreach or return: they are statements, not expressions. ------------------------------------------------------------------------ [2019-03-21 03:11:21] xxalfa at gmail dot com Description: ------------ I don't understand why "goto" is not treated like "require_once"?
