How to generate fixed length key?

[cuixiping]

For example, always generate 6-chars key for id 1 to 1,000,000?

There is no simple way of doing it, you need to dive into the code and rewrite it

PS: I made an ui for shorty: Here

Your UI demo looks pretty! 👍

Hello, it's me again.
I found a way that does this.
In the config.php file there is a $padding variable. But it behaves strange, for example if you set it to 7 the length of the short link will be 5.

IMPORTANT: Changing the padding variable will permanently change all short links

Thank you for your research.
Yes, the $padding is confusing.
I set $padding=8;, tested from 1 to 50.
Results of 1~9, 16, 27, 39 and 42 are 6 chars, others are 7 chars.

I decided to use HashIds for php instead, which can generate fixed length key easily.

There are many implementations of HashIds.
