AMERLOC Posted September 8, 2009 Share Posted September 8, 2009 Hi again, Guys I am New to PHP and I am having a real problem sorting associative arrays when they have arrays of arrays. the array is like this Array ( [AirAvailabilityResults] => Array ( [_size] => 9 [AirAvailabilityReply] => Array ( [0] => Array ( [supplierType] => S [RateInfo] => Array ( [nativeBaseFare] => 763.0 [nativeTotalPrice] => 1753.08 [nativeCurrencyCode] => USD [displayBaseFare] => 763.0 [displayTotalPrice] => 1753.08 [displayCurrencyCode] => USD ) [FlightSegment] => Array ( [0] => Array ( [segmentOutgoing] => true [airlineCode] => US [airline] => US AIRWAYS [flightNumber] => 1498 ) ) [tripType] => R [ticketType] => E ) [1] => Array ( [supplierType] => S [RateInfo] => Array ( [nativeBaseFare] => 763.0 [nativeTotalPrice] => 1767.08 [nativeCurrencyCode] => USD [displayBaseFare] => 763.0 [displayTotalPrice] => 1767.08 [displayCurrencyCode] => USD ) [FlightSegment] => Array ( [0] => Array ( [segmentOutgoing] => true [airlineCode] => US [airline] => US AIRWAYS [flightNumber] => 1498 ) ) [tripType] => R [ticketType] => E ) [cacheKey] => 20a9f112:1239917b36e:-b84 [cacheLocation] => 10.186.168.43:7303 ) ) I am trying to sort the array [AirAvailabilityReply] by the [RateInfo] array. in this example it only shows how to sort an array not an array by a child array: function (compare ($x, $y){ if ($x[1] == $y[1]) { return 0; } else if ($x[1] < $y[1]) { return -1; } else { return 1; } } usort ($products, 'compare'); I have read the forum but there is something I am missing. for example there are 5 availabilty arrays containing each 5 other arrays where I want to sort them via the RateInfo Array so When I do my loops they will be printed in the order cheapest fare. I have finished the program now but and missing the this freakking sorting. Please give me a clue on how to do this and an example would be greatly appreciated.
