Thanks for the comment.

Which extra variables are you referring to?

First of all, i tested it with ONLY text, a really BIG text

Second of all, i didn’t say single quotes aren’t faster, that’s logical, the php engine doesn’t check for variables in it.

What i wanted to point out in this little article is that the overall speed of a page load won’t make much difference, after all, why would a visitor care how much time the php engine needed, he cares how much time the page needs to load.

Good attempt, but this is worthless. This is all done in the PHP lexer, if you want to see the difference you shouldn’t introduce extra variables; you should strip out the pertinent code, and truly benchmark the difference of single-quote vs double quote. Chances are single-quote are faster. Maybe *5* times faster!!! But, 5 times faster on a trivial worthless operation like enabling variable interpolation on a string without variables, is pretty useless in the grand scheme of thing.

Your conclusion, to be logically sound, should read that it isn’t material to the user experience. Not that the speed difference doesn’t exist at all.

Yup, just find out what’s easier for you and keep with that.

Interesting. So the more important thing to do is to be consistent with that as you would with any other part of the code.
