Alea was designed to be very fast (in JavaScript) and to generate non-platform-dependent repeatable sets of random numbers (when supplied with matching seeds). Given portable seeds (strings or integers, for example), numbers generated by the [JavaScript version of alea](https://github.com/coverslide/node-alea/)will exactly match those generated by this PHP port, and vice-versa. Install ------- [](#install) This package is [available on Packagist](https://packagist.org/packages/wikimedia/alea): ``` $ composer require wikimedia/alea ``` Usage ----- [](#usage) ``` use Wikimedia\Alea\Alea; $prng = new Alea(); // add an optional seed parameter $nextRandom = $prng->random(); // or ->uint32() or ->fract53() ``` We also have the ability to sync up two Alea PRNGs (even across platforms) via the `importState` and `exportState` methods. ``` $prng1 = new Alea(200); $prng1->random(); $prng1->random(); $prng2 = Alea::createWithState( $prng1->exportState() ); assert( $prng1->random() === $prng2->random() ); assert( $prng1->random() === $prng2->random() ); assert( $prng1->random() === $prng2->random() ); ``` Acknowledgements ---------------- [](#acknowledgements) The Alea code was written (in JavaScript) by Johannes Baagøe, and packaged for npm by [coverslide](https://github.com/coverslide).
