PHP CLI在数组var之前回显/打印缺少文本...让我发疯

Running a script from the PHP CLI, I am echoing the following line:

echo "
Server {$res['proxy']} | $response | $httpCode | OK";

However this is what is returned:

 | 4.003182888031 | 200 | OK

Its missing out the text before the $res['proxy'] var and the contents of the var (which should be an IP). Ironically though it is still doing the new lines!!

I've tried print instead of echo, ".$res['proxy']." instead of curly braces, single quotes, changing the word 'server', removing the | pipes.

Whatever it is is making a fool out of me! What's going on :(
