Note Submitter: phpdotnetNO_SPAM at electronic-strategy dot com ---- /* Small function to Alphabetically sort Multidimensional arrays by index values of an n dimension array. I have only tested this for sorting an array of up to 6 dimensions by a value within the second dimension. This code is very rough and works for my purposes, but has not been tested beyond my needs. Although a little clunky and not a mathematical type algorithm, it get's the job done. It theoretically overcomes many of the problems I have seen with multidimensional arrays in that it is possible to specify within the function, not by reference :-(, which index you wish to sort by, no matter how many dimensions down. call function by assigning it to a new / existing array: $row_array = multidimsort($row_array); */ function multidimsort($array_in) { $multiarray = array(); $array_out = array(); $loopvalue = 0; /* -1 as traversal of array starts from 0, count() starts from 1 */ $multicount = count($array_in) - 1; /* add the indexes you wish to sort array by to a new array in this case index is two levels down, but shouldn't make a difference if it goes further indexes down. (Not tested!) */ for($i = 0; $i <= $multicount; $i++) { array_push($multiarray, $array_in[$i][2]); //array_push($multiarray, $array_in[$i][2][4]); //array_push($multiarray, $array_in[$i][1][3][7]); } /* alphabetically sort the new array (Ascending in this case) can chage sort to whatever type you like. Even apply user-defined sort. */ asort($multiarray); /* reset internal pointer to beginning of array after above sort */ reset($multiarray); /* traverse new array of index values and add the corresponding element of the input array to the correct position in the output array */ while (list ($key, $val) = each ($multiarray)) { $array_out[$loopvalue] = $array_in[$key]; $loopvalue++; } /* return the output array which is all nicely sorted by the index you wanted! */ return $array_out; }
