Yeah, thats what I also figured but, really, how much can you optimize a constant string literal (which I'm given to understand the single-quote thing is)? Mus

  Single quotes aren't a constant string literal, because they have to parse \'.

    Guesstimate: if someone cares about performance, they should have already installed an opcode cache, which probably wouldn't have to re-parse constant strings. But then thinking: you'd expect constant double quoted strings to also get this treatment, so single quoting still gets you nothing. All the above is void without benchmarks.
