SELECT


//查单条
function get_sub_product()
{
 $res_zz = $pdo->query("SELECT id FROM content WHERE is_publish = 0 LIMIT 1;");
 $rep = $res_zz->fetch();
}
//查多条
function get_sub_product()
{
 $dsn = 'mysql:host=localhost;dbname=bwdb';
 $pdo = new PDO($dsn, 'root', 'root');
 $pdo->query('set names utf8');
 $res_zz = $pdo->query("SELECT product_id FROM sub_product WHERE 1= 1;");
 $rep = $res_zz->fetchAll();
 $product_id_arr = array();
 foreach ($rep as $v) {

INSERT


function add()

UPDATE


function update()

 die("成功!");
 }
 $pdo->rollback();
