64 bit ID Generator

Languages: PHP
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)
$machineID = 0; // Machine ID (aka Server ID no.)
Particle::generateParticle($machineID);Time from Particle ID (w/ millisecond precision)
$particleID = '4611692470816737853';
Particle::timeFromParticle($particleID);
