Via PHPdeveloper.org, I’ve been following Brandon Savage’s blog for a few months. Most recently, he’s posted a pair of excellent articles on productive and useless micro-optimizations. These are code “enhancements” such as “change all print() statements to echo statements because echo is faster”. Brandon takes a look at several popular micro-enhancements and offers his professional opinion on whether they are truly worth your time or not.
I find Brandon’s knowledge of PHP a great resource, and his practical approach is appreciated and it is very evident he develops in the real world rather than in abstract-land. Many of his recent posts have been focused on the beginning php developer. So if you are a newbie or an intermediate (I consider myself the latter), Brandon’s stuff is very much worth your time.
