Rob Thompson has posted about some simple benchmarking he did comparing the speed of a series of "if" statements versus one "switch" with multiple cases.

I got curious about which is actually more efficient at matching a random integer with a set of conditionals. So, I setup a script to create a set of large scripts to test the speed of these different constructs. Using the 'time' command, I measured the speed at which the condition could match a random number.

His results found that the switch statement is generally more than 2 times as fast at matching a simple integer. His tests, however, didn't go through much more than this simple test. It'd be interesting to see what it would do with something more complex (like longer strings or handling the result of an evaluation inside the definition of the switch().

DevShed has posted the latest part of their introduction to PHP series, this time focusing on one of the more useful features of the language - conditionals and loops.

We discussed statements briefly in our last article and even got a sneak peek of an IF-statement. Sure I mean, the image was blurry, and the moment it saw us it ran off into the forest. But we saw it. Honest. So in this article, we're going to take a much closer look at PHP statements and even start learning about loops.

They cover if statements (as mentioned) as well as introduce you to its companions, else and else if. The finish off the article with a brief look at one of the simpler loops, the for loop.
