如何在PHP

Question

我在这个阵列中有点混乱......

其实我有这样的数组

Array
(
    [0] => stdClass Object
        (
            [restaurant_id] => 1
            [food_item] => Chicken Spicy Pizza
        )

    [1] => stdClass Object
        (
            [restaurant_id] => 1
            [food_item] => Pepper Chicken Sandwich
        )

    [2] => stdClass Object
        (
            [restaurant_id] => 6
            [food_item] => Chicken Tikka Roll
        )

    [3] => stdClass Object
        (
            [restaurant_id] => 6
            [food_item] => Grilled Chicken
        )

)

这里我需要创建逗号分隔值food_item并且必须有一个条件，具有相同restaurant_id的数组也合并..

即; ..

我的最终数组应该是这样的..

Array
(
    [0] => stdClass Object
        (
            [restaurant_id] => 1
            [food_item] => Chicken Spicy Pizza,Pepper Chicken Sandwich
        )

    [1] => stdClass Object
        (
            [restaurant_id] => 6
            [food_item] => Chicken Tikka Roll,Grilled Chicken
        )
)

任何建议？!! ...

谢谢！。

让您的实际数组位于名为// Controller for binding galleries to view app.controller('newMainCtrl', function($scope, ImageGalleriesService) { $scope.galleries = ImageGalleriesService.getGalleries(); $scope.$watch(function(){ return ImageGalleriesService.getGalleries(); }, function(newVal){ $scope.galleries = newVal; }); }); // Single Image controller app.controller('imageCtrl', function($scope, ImageGalleriesService) { $scope.imageinit = function(value) { $scope.imageitem = value; }; }); // Gallery controller app.controller('galleryCtrl', function($scope, ImageGalleriesService) { $scope.init = function(gallery) { $scope.gallery = gallery; }; $scope.duplicate = function() { ImageGalleriesService.addImageGallery($scope.gallery, null, 2); }; }); // Service that holds all the galleries app.service('ImageGalleriesService', function() { var imagegalleries = []; this.getGalleries = function(){ return imagegalleries; }; this.addImageGallery = function(imagegallery){ imagegalleries.push(imagegallery); }; }); 的变量中。所以这是代码

$actualArr

您可以使用array_reduce来完成它

$myArr = array_reduce($myArr, function ($carry, $item) {
    if (!isset($carry[$item->restaurant_id])) {
        $carry[$item->restaurant_id] = $item;
    } else {
        $carry[$item->restaurant_id]->food_item .= ',' . $item->food_item;
    }
    return $carry;
}, array());
