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) { $product_id_arr[] = $v['product_id']; } return $product_id_arr; }
INSERT
function add() { try { $pdo->beginTransaction(); $reb = $pdo->prepare("INSERT INTO `content` (`id`,`content`) VALUES(:version_id,:content);"); $reb->bindParam(':version_id', $version_id, PDO::PARAM_INT); $reb->bindParam(':content', $content, PDO::PARAM_STR); $type_id = 1; $reb->bindParam(':type_id', $type_id, PDO::PARAM_INT); $reb->bindParam(':cdate', $time, PDO::PARAM_STR); $reb->bindParam(':mdate', $time, PDO::PARAM_STR); if ($reb->execute() > 0) { $pdo->commit(); die("成功!"); } $pdo->rollback(); die("失败!"); } catch (PDOException $ex) { echo($ex->getMessage()); } } function add($res_arr) { $dsn = 'mysql:host=localhost;dbname=db'; $pdo = new PDO($dsn, 'root', 'root'); $pdo->query('set names utf8'); $value = ''; date_default_timezone_set("Asia/Shanghai"); //时区 $time = date('Y-m-d h:i:s'); foreach ($res_arr as $k => $v) { $hash = md5($v['ProductID'] .

UPDATE
function update() { try { $pdo->beginTransaction(); $is_publish = 1; $req = $pdo->prepare("UPDATE `content` SET is_pub=:is_pub,mdate=:mdate WHERE id = :id;"); $req->bindParam(':is_publish', $is_publish, PDO::PARAM_INT); $req->bindParam(':id', $version_id, PDO::PARAM_INT); $req->bindParam(':mdate', $time, PDO::PARAM_STR); if ($req->execute()) { $pdo->commit(); die("成功!"); } $pdo->rollback(); die("失败!"); } catch (PDOException $ex) { echo($ex->getMessage()); } }
