**PikaID** is a tiny PHP library that creates **unique, short, and sortable IDs** —
a modern alternative to UUIDs for your databases, APIs, and distributed systems.

💡 Example Use Case
------------------

[](#-example-use-case)

Imagine you’re building a **web app** where users can post messages or create orders.
Each new item needs a **unique ID** so your system can recognize it.

If you use normal numbers (`1, 2, 3…`), you can have **conflicts** when several servers create data at the same time.
If you use UUIDs, you get **long, messy IDs** that are hard to read and don’t follow creation time.

**PikaID solves this:**

- Every new ID is **unique**, even if many servers create them at once.
- IDs are **short**, so they look clean in URLs or logs.
- They are **time-ordered**, so when you list data, the newest appears last or first automatically.

You can use PikaID to:

- Identify **users**, **orders**, **invoices**, or **API resources**.
- Name **uploaded files** safely.
- Tag **events** or **logs** across distributed systems.

> **In short:** PikaID gives you clean, safe, and sortable IDs for anything that needs a unique reference.

Pikaid (PHP)
============

[](#pikaid-php)

**Small · Sortable · Secure ID generator**

This is the **official PHP implementation.** Fully compliant with v1.0.3.

Pikaid is a **26-character, lowercase Base36 identifier**, composed of:

- **7-character timestamp** (seconds since epoch)
- **19-character cryptographically secure randomness**

It’s a **modern, compact alternative** to UUID and ULID:

- Lexicographically sortable
- Collision-resistant
- Compact binary form (`BINARY(17)`)
