How much CPU time does each of those spend? There are also a bunch of other optimization tricks you can do like 'using single quotes instead of double quotes', but (I may speak for only myself here) I don't like "micro-optimization" (as people tend to call this). Check out this post: http://fabien.potencier.org/article/8/print-vs-echo-which-one-is-faster Also I want to state that I am concentrating on getting basic knowledge out there so people can grow on that. Optimization of code should of course be considered, but I believe it's better to actually get stuff done. hardware is also cheap today. One other reason that I am using print is because I also do a lot of perl, and the convenience and ignorance is bliss. :-D I agree with you, echo is on average 20% faster than print, but please just hear me out on my
