elias Posted August 19, 2009 Share Posted August 19, 2009 Hi guys and gals! Lets see if I can explain the problem.... I have collated data from various tables to arrive a something like this: CompetitionRankShortLongTotal Barcelona2101525 Madrid1151530 Valencia3121022 I would like to sort this data by "Rank", "Short", "Long" or "Total". To that effect I have managed to introduce the data in to a multidimensional array with the keys values such as: $results[$competition]["elements"] - where $results is the multi-array $competition are teh sub arrays (madrid, barcelona, valencia) "elements" are the values of "rank", "short", "long" and "total" so, echo $results["madrid"]["total"]; // yields 30 //sorry to go on, but I need //to get my head around this still now to the question, how can I sort by "rank", say. have tried array_multisort() but found it only sorts by "row" so to speak. I can sort "Rank", "Short", "Long", "Total" or "2", "10", "15", "25" but not as I want by "column": "25, "30", "22" I have considered dumping everything back into a dummy db table, but thought "there must be a better way". also, thought of "flipping" teh table so teh rows are columns and vice-versa, but cant even begin to think how to do it, apart from creating a function() which would be a last resort. thoughts, leads, suggestions - welcome! thx and keep up the good work! elias Link to comment https://forums.phpfreaks.com/topic/171038-flipping-and-sorting-a-multi-dimensional-array/ Share on other sites More sharing options...
msinternet Posted August 19, 2009 Share Posted August 19, 2009 Hi, if it was me I would use numerical indices and maybe a lookup array. Then you can loop through with a for loop to build a second inverted array. Or, in a similar way use a foreach loop to go down a layer and build the second array.
