在foreach循环中删除重复项

Question

在结果中，下拉菜单中有一些重复的内容。你知道如何解决吗？

购买array_unique吗？

谢谢

示例：

<select name="boxtal_operator" id="sortDropDownListByText" class="form-control">
    <option value="0">--- Select ---</option>
    <option value="CHRP-1456S">AGAY / L'ATELIER FLORAL D'AGAY / 125 BD DE LA PLAGE / CHRP-1456S</option>
    <option value="CHRP-1456S">AGAY / L'ATELIER FLORAL D'AGAY / 125 BD DE LA PLAGE / CHRP-1456S</option>
    <option value="CHRP-1456S">AGAY / L'ATELIER FLORAL D'AGAY / 125 BD DE LA PLAGE / CHRP-1456S</option>
    <option value="SOGP-I3171">AGAY / PROXI / 1318 BD DE LA 36EME DI DU TEXASLE DRAMONT / SOGP-I3171</option>
    <option value="SOGP-I3171">AGAY / PROXI / 1318 BD DE LA 36EME DI DU TEXASLE DRAMONT / SOGP-I3171</option>
    <option value="SOGP-I3171">AGAY / PROXI / 1318 BD DE LA 36EME DI DU TEXASLE DRAMONT / SOGP-I3171</option>
</select>

下面的php代码允许产生此结果。

$operator_code = ['POFR', 'MONR', 'SOGP', 'Chrono', 'CHRP', 'IMXE', 'UPSE', 'PUNT'];

$result_carrier_code[] = ['id' => '0', 'text' => Core::getDef('text_select')];

    foreach ($operator_code as $operator)
    {
        $list_point = $this->boxtaleShop->getListPoint($country_iso, $code_postal, $city, $operator);

        foreach ($list_point as $carrier)
        {
            if (is_array($carrier)) {
                foreach ($carrier as $item)
                {
                    if (is_array($item['points'])) {
                        foreach ($item['points'] as $points)
                        {
                            if (is_array($points)) {
                                $result_carrier_code[] = [
                                    'id' => $points['code'],
                                    'text' => $points['city'] . ' / ' . $points['name'] . ' / ' . $points['address'] . ' / ' . $points['code']
                                ];
                            }
                        }
                    }
                }
            }
        }
    }
