步骤1:打开navicat连接数据库工具，顶部的文件栏-导出结果-勾选导出密码-导出
步骤2：导出结果使用NotePad++或文本打开，找到，数据库对应的的Password="995E66F64A15F6776""的值复制下来
<Connection ConnectionName="no" ProjectUUID="" ConnType="MYSQL" OraConnType="" ServiceProvider="Default" Host="1" Port="3306" Database="" OraServiceNameType="" TNS=""
MSSQLAuthenMode="" MSSQLAuthenWindowsDomain="" DatabaseFileName="" UserName="web_test" Password="995E66F64A15F6776
步骤3：打开在线工具，复制下面代码粘贴，修改代码倒数第二行代码：$decode = $navicatPassword->decrypt('995E66F64A15F6776886C4C7A0C0BF16');
步骤4：点击代码在线运行工具，运行
在线查看工具：代码在线运行 - 在线工具
一下为php 代码，复制运行，修改代码倒数第二行代码，
