Mysql php中使用数组过滤查询

我正在使用数组值创建一个过滤器查询。它可以工作。但是如果数组值为null，则它不起作用。如果我从头开始创建，它甚至可以用于null。我想动态地创建它

这是我的代码

            $city_array=array('yangon','mandalay','myeik');
            $data_city=implode("','",$city_array);          

            $brand_array=array('huawei','samsung','sony');
            $data_brand=implode("','",$brand_array);

            $camera_array=array('rear camera');
            $data_camera=implode("','",$camera_array);

            $operator_array=array('mpt');
            $data_operator=implode("','",$operator_array);

            $size_array=array('');
            $data_size=implode("','",$size_array);

            $ram_array=array('');
            $data_ram=implode("','",$ram_array);

            $memory_array=array('');
            $data_memory=implode("','",$memory_array);

            $feature_array=array('');
            $data_feature=implode("','",$feature_array);


            $query = mysql_query ("

现在还不清楚你说的“有效”和“无效”是什么意思。什么可能是空值也不明显（

$city\u array

，

$city\u array[0]

，或者有些可能只是

$city\u array

中的一个值）。这段代码的主要问题是，如果其中一个数组中的一个值包含引号（'），您将得到一个断开的mysql查询。什么可能是空值也不明显（
