LID
===

[](#lid)

LID (LongID) is a 64-bit number used to identify rows in a database.
Made specifically for use with BIGINT/LONGINT in databases. Includes a checksum to verify data.

Note: v1.x is not compatible with v0.x.

Install
-------

[](#install)

```
composer require choval/lid^1.0
```

Format
------

[](#format)

It is built using a base 62:

```
0123456789
abcdefghijklmnopqrstuvwxyz
ABCDEFGHIJKLMNOPQRSTUVWXYZ

```

- Except the web format, see [Web](#web).

The checksum (Damm) is the first character.

```

Web
---

[](#web)

A different base is used for the web format.

Altough longer in length due to a shorter base, it is easier for dictation (across dialects) and more error friendly for OCR engines.

Alias characters are replaced.

```
0 - zero - alias: OoDQ
1 - one - alias: IiLl
2 - two - alias: Zz
3 - three
4 - four - alias: AYy
5 - five - alias: Ss
6 - six - alias: Gb
7 - seven - alias: T
8 - eight - alias: BRg
9 - nine - alias: q
C - charlie - alias c
E - echo - alias e
F - foxtrot - alias f
H - hotel - alias h
J - juliett - alias j
K - kilo - alias k
N - november - alias: Mmn
P - tango - alias: p
V - victor - alias: UuWw
X - xray - alias x

```
