First, if you're developing this application, I strongly advice not
messing with caching until you're ready to deploy. In particular, you
do $banners_tmp = Cache::read('banners'); even if it returns empty?
Maybe you're looking at only your cached version all the time, not
what's in your database?Second, MySQL has random functions so you can put that inside your SQL code. You can have conditions like, "... SORT BY RAND() LIMIT 1..." Third, array_rand() doesn't look to be a cakePHP function either. Try writing a function that takes some data and returns a random piece of it. Then input your Position data into that function, basically break the task at hand into two: the cakePHP part of retrieving data, and the non-cakePHP part of taking a random element from an array. that is, if you don't want to use the advise above and incorporate RAND() into your SQL query. _V On May 17, 8:50 am, HK <[email protected]> wrote: > Hello, > > I have a strange problem with one of my applications. > > Consider the following code: > function getBanner() { > $banners_tmp = Cache::read('banners'); > if(empty($banners_tmp)) > { > $this->loadModel('Position'); > $this->Position->cacheBanner(); > $banners_tmp = Cache::read('banners'); > } > > //srand(floor(time() / (60*60*24))); > //debug(rand() % count($banners_tmp)); > > //return $banners_tmp[rand() % count($banners_tmp)]; > return $banners_tmp[array_rand($banners_tmp)]; > } > > array_rand always return the first element of my array.
