json数组元素到数组

Question

 $cuisines = RestaurantProfile::select('cuisines')->get();
    $cuisines_array = array();
    foreach ($cuisines as $cuisine) {
        $string = implode(",",json_decode($cuisine, true));
        $array = explode(",", $string);
        foreach ($array as $single) {
             if (!in_array($single, $cuisines_array)) {
                 $cuisines_array[] = $single;
             }
         } 
    }
    dd($cuisines_array);

我希望$ cuisines_array有类似

的东西

array:33 [▼
0 => "Afghani"
  1 => "Mughlai"
  2 => "Chinese"
  3 => "Indian"
  4 => "continental"
  5 => "south indian"
  6 => "mughlai"

但我在屏幕截图中显示：output screenshot

表中的我的美食属性是database table。 任何线索？

您可以使用array_slice()：

...
foreach (array_slice($array, 0, 6) as $single) {
...

array_slice()  

  

返回数组中数组的元素序列   偏移和长度参数
