Hi Fellows, I figured out, that PHP5 runs faster when I am not inherit

    classes,

I hope I use the right word. I mean the class sub_class extends main_class notation. As well I figured out, that I in most cases should references in foreach loops. like foreach($array as $key => &$value) { } Lots of memory is saved by that. Now I would like to know, what other speed improvements might be possible. What about autoload of classes, will it improve speed when I throw the code out? Are there other things I should take care of. I would like to know as much as possible. Please go deep into

    your-

self and tell me every little thing on how you improved your

    applica-

tions for speed and memory optimisation, to make this thread

    the best

compendium on performance and memory optimisation. Thank you very much, fellows and a merry merry christmas! I never optimize code unless there's a problem with its

    performance...

Why one would tweak code endlessly to maximize performance when

    that's

not needed is beyond me... But maybe I'm just a Luddite.

    Hardware is cheaper than man hours. Just throw more CPU power at the
    problem.

thats only true until poorly designed software cant be spread across machines due to a monolithic nature. get an opcode cache and index the database; that will probly absolve any noticeable speed problems. -nathan Well obviously you can always write horrible code but if you write code that is easy to maintain it's usually not that kind of code. -- Michael McGlothlin Southwest Plumbing Supply
