简易好用的mysqli驱动器与结果集，带自动事务，参数转义

项目介绍

简易好用的mysqli驱动器与结果集，带自动事务，参数转义

说明文档

example.php 里有范例代码

1. 连接数据库

方法1：使用构造方法连接

$mysqli = new MysqliDriver(['username' => 'root', 'password' => '123456', 'database' => 'test']);

方法2：使用connect连接

$mysqli = new MysqliDriver();
$conf = ['username' => 'root', 'password' => '123456', 'database' => 'test'];
$mysqli->connect($conf);

方法3: 使用类文件里的默认值连接

$mysqli = new MysqliDriver();
$mysqli->connect();

2. 执行查询

select

$query = $mysqli->query('select * from `money`');
print_r($query->result());

update insert delete

$status = $mysqli->query('update `money` set number = number - ? where uid = ?', 10, 100);
if($status){
    echo $mysqli->affectedRows;
}

3. 结果集

返回全部记录，对象

$query = $mysqli->query('select * from `money`');
print_r($query->result());

返回全部记录，数组

$query = $mysqli->query('select * from `money`');
print_r($query->result(Library\MysqliResult::MYSQLI_ARRAY));

返回单独一行结果。如果你的查询不止一行结果，它只返回第一行

$query = $mysqli->query('select * from `money`');
print_r($query->row());

4. 事务

事物中的sql执行失败，会自动回滚

注意: 默认update/insert/delete的affected_rows为0时事物也会自动回滚，如果你不想这样，请配置MysqliDriver::backZeroAffect = false;

$mysqli->transStart();
$mysqli->query('update `money` set number = number - ? where uid = ?', 10, 100);
$mysqli->query('insert `history`(uid, number) values(?, ?)', 100, -10);
$mysqli->transComplete();
echo 'Transaction execution status: ' . ($mysqli->transStatus() ? 'true' : 'false');
