PHP extension to generate unique string ID based on numbers

The content shared with you in this article is a PHP extension that generates a unique string ID based on numbers. It has a certain reference value. Friends in need can refer to it.

Hashids is a method that can generate unique string IDs. Non-sequential string ID numbers, it can also decrypt these IDs, you can use it to encrypt numeric IDs that you don't want to expose to users.

Installation

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

You can set some options in php.ini, or you can set them in the constructor, but I recommend you set them in php.ini so that you can have Better performance.

[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

Quick Start

$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]

Performance

Originally there was a function implemented by pure PHP code, now it is encapsulated into a PHP extension, and the performance is improved compared to the pure PHP version About a hundred times more

##Others

$hashids = new Hashids();

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

Parameters of the construction method

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

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

16 hexadecimal encryption and decryption

$hashids = new Hashids();

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