PHP基于PDO扩展操作mysql数据库示例

本文实例讲述了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

(

,

) 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['TradeTyp/**【关于环境方面，我觉得DOCKER是非常合适和快速部署的一个方式】**/e'] . "','" . $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

(

,

,

,

,

,

,

,

,

,

, "

,

,

,

,

,

,

,

,

,

,

,

) 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

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());

}

}

希望本文所述对大家PHP程序设计有所帮助。
