It seems to be returning the difference in length instead of restricting the output to -1, 0, or 1. I am using Zend's Debian nightly build: PHP 7.0.0-dev (cli) (built: Jun 19 2015 19:09:04) Test script: --------------- // Here's a direct example from the RFC, which says this // should evaluate to 1. However, I get 3 instead: echo [1, 2, 3] <=> []; // Here are some other examples: echo [1, 2, 3, 4, 5] <=> []; // 5 echo [] <=> [1, 2, 3, 4, 5]; // -5 echo [1, 2, 3, 4, 5] <=> [1]; // 4 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69891&edit=1
