PHP基于PDO扩展操作mysql数据库示例

PHP基于PDO扩展操作mysql数据库。分享给大家供大家参考，具体如下：

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'] . "-" . $v['CategoryID'] . "-" . $v['CategoryName']);      $value .= "('" . $v['ProductID'] . "','" . $v['CategoryID'] . "','" . $v['CategoryName'] . "','" . $v['ProductName'] . "','" . $v['Abbreviation'] . "','" . $v['SubscribeStatus'] . "','" . $v['ProductStatus'] . "','" .        $v['BrandID'] . "','" . $v['BrandName'] . "','" . $v['TradeType'] . "','" . $v['ProductModel'] . "','" . $v['UPCCode'] . "','" . $v['Weight'] . "','" . $v['Summary'] . "','" .        $v['LongDescription'] . "','" . $v['BuyNotice'] . "','" . $v['PackingList'] . "','" . $v['DefaultImage'] . "','" . $v['Keywords'] . "','" . $v['VendorID'] . "','" . $v['StoreID'] . "','" .        $v['CurrentPrice'] . "','" . $v['AvailableQty'] . "','" . $hash . "','" . $time . "','" . $time . "'),";    }    $vv = substr($value, 0, strlen($value) - 1);    try {      $pdo->beginTransaction();      if (!empty($vv)) {        $reb = $pdo->prepare("REPLACE INTO `product_list` (`product_id`, `category_id`, `category_name`, `product_name`, `abbreviation`, `subscribe_status`, `product_status`, `brand_id`, `brand_name`, `trade_type`, "          . "`product_model`, `upc_code`, `weight`, `summary`, `long_description`, `buy_notice`, `packing_list`, `default_image`, `keywords`, `vendor_id`, `store_id`, `current_price`, "          . "`available_qty`, `hash`, `cdate`, `mdate`) VALUES $vv;");        if ($reb->execute() > 0) {          $pdo->commit();          return 1;        }      }    } catch (PDOException $ex) {      $pdo->rollback();    }    return -1;  }

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());    }  }
