使用Hashids隐藏自增ID

通过Composer安装Hashids
[root@localhost ~]# mkdir Hashids

[root@localhost ~]# cd Hashids/

[root@localhost Hashids]# composer require hashids/hashids

Do not run Composer as root/super user! See https://getcomposer.org/root for details

Continue as root/super user [yes]? yes

Generating autoload files

[root@localhost Hashids]# 

 

把/Hashids目录复制到项目，PHP文件引入/Hashids/vendor/autoload.php即可使用Hashids，下面是demo代码：

<?php
require_once __DIR__ . '/Hashids/vendor/autoload.php';

// 实例化时可加盐及指定密文最短长度
$hashids = new \Hashids\Hashids('俺是加盐字符串，俺可以更改为任意字符串！', 32);

//========== 单个ID加密 ==========//
$id       = 12345; // 注意只能使用数字或数字字符串，如果字符串包含字母则会报Notice错误
$idEncode = $hashids->encode($id);
$idDecode = $hashids->decode($idEncode)[0]; // 注意decode()方法后面要加“[0]”
echo "原始ID：{$id}" . PHP_EOL;       // 原始ID：12345
echo "加密ID：{$idEncode}" . PHP_EOL; // 加密ID：bv9wj4yWdO0xXQ4WwB1qVPDrGl8nNoJ3
echo "解密ID：{$idDecode}" . PHP_EOL; // 解密ID：12345

//========== 多个ID加密 ==========//
$idArr       = array(12345, 10086, 67890);
$idArrEncode = $hashids->encode($idArr); // 多个ID加密的结果也是一串字符串
$idArrDecode = $hashids->decode($idArrEncode);
print_r($idArrDecode);
