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
$hashids = new Hashids();
$hash = $hashids->encode(1, 2, 3, 4, 5); // ADf9h9i0sQ
$hash = $hashids->encode([1, 2, 3, 4, 5]); // ADf9h9i0sQ
Copy after login
Parameters of the construction method$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
