note 26583 modified in function.array-push by vrana

Another associative array sorter. Will handle null arrays, and should correctly handle multidimensionals. Essentially, it pulls all the keys into an array, randomizes that array, then spits out a reconstructed array based on the randomized keys. I would have used array_keys() instead of the first foreach(), but unfortunately the array returned gets spit back in hash order, not array order. My particular needs required me to have reproducable randomizations based on specific mt_srand() values. For most people who just need a random array output with no reproduction, you can substitute the line beneath. <?php function assocArrayShuffle($inarray) { if(!$inarray) return $inarray; $keys = array(); $rkeys = array(); foreach($inarray as $k => $v) $keys[] = $k; // OR... $keys = array_keys(); while(count($keys)>0) { list($k) = array_splice($keys, mt_rand(0, count($keys)-1), 1); $rkeys[] = $k; } foreach($rkeys as $k => $v) $outarray[$v] = $inarray[$v]; return $outarray; } ?> --was-- Another associative array sorter.
