@Peter Uhm, I still see ‘foreach’ giving a +632% overhead in Modify Loops. What did I lose?

the ‘foreach’ results are now the fastest.

@nikan

That’s for the Read Loop, when you just want to traverse an array and do some stuff with its values. Check the Modify Loop, that’s what I meant.

You confused me. The conclusion at the phpbench.com is quite the opposite from yours:

“In all cases I’ve found that the foreach loop is substantially faster than both the while() and for() loop procedures. One thing to note is that when using an entire loop from the start it’s extremely good to use the reset() function in all examples”

What am I (or you) misinterpreting?

@Vangelis

Also noticed that pre-calculated array lengths, a long-standing optimization for loops, actually have no positive effect in PHP efficiency. Quite a shock too.

I’m right with you on the quick coding bit, but experience has proven us wrong – when coding in a hurry, you’ll pay for it later.

Twitter, anyone?

That’s old news but nobody cares. By the time you optimize a web application you can get a 2x faster server for the same money. So… Speed of coding not speed of code. Foreach rocks
