# Particle

#### Language: PHP

#### 64bits int Time Based ID Generator

### Uncoordinated

For high availability within and across data centers, machines generating ids should not have to coordinate with each other.

### Solution

* PHP (tested on v7.1.8)

* Particle Id (64 bits) is composed of:

  * time - 42 bits (millisecond precision w/ a custom epoch)

  * configured machine id - 10 bits - up to 1024 machines

  * sequence number - 12 bits - up to 4096 random numbers

### System Clock Dependency

You should use NTP to keep your system clock accurate.

## How to use it

#### Generate Particle ID

Change const EPOCH in particle class to today epoch time w/ millisecond (13 digits)

```PHP

	$machineID = 0; // Machine ID (aka Server ID no.)

	Particle::generateParticle($machineID);

```

#### Time from Particle ID (w/ millisecond precision)

```PHP

	$particleID = '4611692470816737853';

	Particle::timeFromParticle($particleID);

```
