PHP mysqli commit() 函数

示例 - 面向对象风格

关闭自动提交，进行一些查询，然后提交查询：

<?php
$mysqli = new mysqli("localhost","my_user","my_password","my_db");

if ($mysqli -> connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}

// Turn autocommit off
$mysqli -> autocommit(FALSE);

// Insert some values
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Peter','Griffin',35)");
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Glenn','Quagmire',33)");

// Commit transaction
if (!$mysqli -> commit()) {
echo "Commit transaction failed";
exit();
}

$mysqli -> close();
?>
