PHP PDO，事務處理

pdoTransaction.php（通過異常的方式復原）:

<?php
//采用預處理+事務處理執行SQL操作
//1.連接配接資料庫
try{
	$pdo = new PDO("mysql:host=localhost;dbname=資料庫名","root","密碼");
	$pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);  //以異常方式報錯
}catch(PDOException $e){
	die("資料庫連接配接失敗".$e->getMessage());
}
//2.執行資料操作
try{
	//開啟事物
	$pdo->beginTransaction();
	$sql = "insert into stu(id,name,sex,age) values(?,?,?,?)";
	$stmt = $pdo->prepare($sql);
	//傳入參數
	$stmt->execute(array(null,"test4","w",11));
	$stmt->execute(array(null,"test5","w",11));
	$stmt->execute(array(null,"test3","w",11));
	//送出事物
	$pdo->commit();
}catch(PDOException $e){
	die("執行失敗".$e->getMessage());
	$pdo->roolback();
}
           

pdoTransaction.php（通過foreach的方式復原）:

<?php
//采用預處理+事務處理執行SQL操作
//1.連接配接資料庫
try{
	$pdo = new PDO("mysql:host=localhost;dbname=資料庫名","root","密碼");
}catch(PDOException $e){
	die("資料庫連接配接失敗".$e->getMessage());
}
//2.執行資料操作

//開啟事物
$pdo->beginTransaction();
$sql = "insert into stu(id,name,sex,age) values(?,?,?,?)";
$stmt = $pdo->prepare($sql);
$datalist = array(
	array(null,"test9","w",11),
	array(null,"test10","w",11),
	array(null,"test11","w",11)
);
$isCommit = true;

foreach($datalist as $data){
	$stmt->execute($data);
	if($stmt->errorCode()>0){	
		$pdo->roolback();
		$isCommit = false;
		break;
	}
}

if($isCommit){
	//送出事物
	$pdo->commit();
}
