arrays - 数组到字符串

Question

我有一个array(1) { [0]=> array(1) { ["id"]=> string(1) "2" } }

我只得到一个值，怎么能把它分解成一个字符串？

模型：

$table = $this->_table_products_manufacturers;
        $query  = $this->db->query("SELECT $table.id FROM $table WHERE $table.id = $manufacturer_id");

        return $query->result_array();

Answer 1

就像是：

$table = $this->_table_products_manufacturers;
$query = $this->db->query("SELECT $table.id FROM $table WHERE $table.id = $manufacturer_id");
$result = $query->result_array();
return $result[0]['id'];

会有帮助吗？
