<?php const WTF=array(); if (defined('WTF') // Just a constant && ! is_scalar(WTF) // but is non scalar && WTF !== null // and is not null (it would be too easy) && ! is_resource(WTF) // and is non resource (surprised!) ) { echo "WTF! This is ", gettype(WTF); }
Output for git.master, git.master_jit, rfc.property-hooks
