I found this rather interesting page on PHP optimization: http://www.php.lt/benchmark/phpbench.php. It concludes that the difference between single and double quotes is negligible altogether, unless you're using an unescaped $ and *not* referring to a variable (which understandably seems to confuse the interpreter a bit). I have no idea what version of PHP that is, however.

Yes, the difference in execution time is negligible, as I said in my previous post. However, the difference in parse time is said to be significant.
