php - 如何在由客户分隔符分隔的单个列中一起显示两个组连接列

Question

下面是显示表格的 Controller 函数

$rec = DB::table('recipe_list')
    ->select('recipe_list.recipe_id', 'recipe_list.Recipe_name',
        'recipe_list.Recipe_desc', 'recipe_list.Recipe_duration',
        DB::raw('group_concat(distinct ing_list.Ing_name separator ",") as recipe_ingredients'),
        DB::raw('group_concat(distinct recipe_inglist.quantity  separator ",") as ingredients_amount'),
        'recipe_cusine.Cusine_name', 'recipe_type.Recipe_type_name', 'recipe_list.image',
        DB::raw(' count(distinct likerecipes.id) as likes'))
    ->join('recipe_inglist', 'recipe_list.recipe_id', '=', 'recipe_inglist.Recipe_id')
    ->join('ing_list', 'recipe_inglist.Ing_id', '=', 'ing_list.ing_id')
    ->join('recipe_cusine', 'recipe_list.Recipe_cusine_id', '=', 'recipe_cusine.cusine_id')
    ->join('recipe_type', 'recipe_list.Recipe_type_id', '=', 'recipe_type.Recipe_typeID')
    ->join('likerecipes', 'recipe_list.recipe_id', '=', 'likerecipes.recipe_id')
    ->where('recipe_list.recipe_id', '>=', '1')
    ->groupBy('recipe_list.recipe_id', 'recipe_list.recipe_name', 'recipe_list.recipe_desc', 'recipe_list.recipe_duration', 'recipe_cusine.Cusine_name', 'recipe_type.Recipe_type_name', 'recipe_list.image')->get();

表格输出是 Recipes Table

但是我想要的输出是这样的:

|Recipe_id|Name|Description|Cusine|Type |Ingredient        |
|   1     |blah|blahblahbla| bla  | bla | 20 gm of garlic,
                                        | 500 gm of chicken,
                                        | 30 gm of onion,

这是我的 recipe_inglist 表 recipe_inglist

我建议你使用 php 代码，

像这样，

你有$rec数据，然后执行下面的代码，

foreach ($rec as $k => &$v) {
    $names  = explode(",", $v->recipe_ingredients);
    $amount = explode(",", $v->ingredients_amount);
    $temp   = [];
    foreach ($names as $key => $value) {
        $temp[] = $amount[$key] . ' of ' . $value;
    }
    if ($temp) {
        $v->ingredient = implode(",", $temp);
    }

}

我在哪里创建 ingradient 字段，例如20 克大蒜、500 克鸡肉、30 克洋葱作为值(value)。
