在使用get方法php提交表单％5B％5D时如何编码url

Question

我正在使用get方法php进行多国搜索。在我的第一页中，我将此代码用于ex：<select id="country" name="nationality[]" multiple="multiple" class="form-control">

在我的结果页面中，URL编码为：url?name=Ganesh&nationality%5B%5D=Italian&nationality%5B%5D=French

if(isset($_GET['nationality'])) {
    $are='all';

    if($_GET['nationality']!=$are) {

        $loc = $_GET['nationality'];
        $nationality = array($loc);

        $comma_separated = implode(",", $nationality);

        $items = preg_split("/[,\\t]+/", $comma_separated);
        $sqlItems = array();
        foreach ($items as $item) {
            $sqlItems []= "'" . ($item). "'";
        }

    }
}
