This article feels very hastily thrown together.

No mention of APC and they didn't even bothering to discuss profilers beyond a link (which doesn't even return xhprof on the first page!)

The getter/setter thing is the perfect definition of a premature optimization. Making that optimization will result in an infinitesimally small gain compared to what could be had optimizing bad SQL and caching deficiencies.

Agreed. Said other bits in another comment, but:

-mysql_query()? BAD GOOGLE WEBMASTER, NO COOKIE FOR YOU. Seriously - there is no good reason not to use PDO, or at least MDB2. (Doctrine is better, but it's just a superset of PDO.)

-References are a modern PHP programmer's (quiet you, stop laughing!) best friend. "Don't use shortened variables because you'll copy data! Just reuse the $_POST['barf']!" Never mind that $foo = &$_POST['barf'] achieves both goals...

[smalyshev]

$foo = $_POST['barf'] does not copy data.

Agreed. Hardly any of it is specific to PHP ("use the latest version", No SQL in a loop, use caching, use a profiler) and the stuff that is seems of marginal benefit.

They forget that there are tools to create quick getters and setters
