PHP 扩展之根据数字生成唯一的字符串 ID

$ git clone https://github.com/cdoco/hashids.phpc.git
$ cd hashids.phpc
$ phpize && ./configure && make && make install

[hashids]
extension=hashids.so

//默认是空字符串
hashids.salt=cdoco

//默认长度是 0
hashids.min_hash_length=20

//默认是 abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890
//你可以自己设置它，比如你使用全部小写的字符
hashids.alphabet=abcdefghijklmnopqrstuvwxyz

$hashids = new Hashids();

$hash = $hashids->encode(1, 2, 3, 4, 5); // ADf9h9i0sQ
$numbers = $hashids->decode($hash); // [1, 2, 3, 4, 5]

//或者你可以用静态方法调用
$hash = Hashids::encode(1, 2, 3, 4, 5); // ADf9h9i0sQ
$numbers = Hashids::decode($hash); // [1, 2, 3, 4, 5]

$hashids = new Hashids();

$hash = $hashids->encode(1, 2, 3, 4, 5); // ADf9h9i0sQ
$hash = $hashids->encode([1, 2, 3, 4, 5]); // ADf9h9i0sQ

new Hashids(string $salt, int $min_hash_length, string $alphabet);

//example
new Hashids("this is salt.", 20, 'abcdefghijklmnopqrstuvwxyz');

$hashids = new Hashids();

$hash = $hashids->encodeHex('FFFFDD'); // rYKPAK
$hex = $hashids->decodeHex($hash); // FFFFDD
