What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you generate YouTube-looking IDs from numbers. These IDs are short, can be generated from a custom alphabet and are guaranteed to be collision-free. Read more .

This is what they look like:

PHP

PHP code is located at https://github.com/sqids/sqids-php

To encode & decode:

$sqids = new Sqids();
$id = $sqids->encode([1, 2, 3]); // "86Rf07"
$numbers = $sqids->decode($id); // [1, 2, 3]

Randomize IDs by providing a custom alphabet:

$sqids = new Sqids('FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE');
$id = $sqids->encode([1, 2, 3]); // "B4aajs"
$numbers = $sqids->decode($id); // [1, 2, 3]

Enforce a minimum length for IDs:

$sqids = new Sqids('', 10);
$id = $sqids->encode([1, 2, 3]); // "86Rf07xd4z"
$numbers = $sqids->decode($id); // [1, 2, 3]
