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 `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());
}
}
