Load WordPress from a CLI not in the global scope

wp-cli.php

<?php

// When loading WP from phpunit, phpunit doesn't run WP in the global scope.
// This breaks WP. This is an attempt to fix it.

function de_globalize_wp() {
	// pretend this is apache
	// I use $_SERVER['HTTP_HOST'] or a file called "host" to get the right DB settings
	$_SERVER['HTTP_HOST'] = trim(file_get_contents(__DIR__ . '/host'));

	$_SERVER["REQUEST_METHOD"] = 'GET';
	$_SERVER["SERVER_PROTOCOL"] = 'HTTP/1.0';
	$_SERVER["SERVER_PORT"] = '80';
