Unique Integer Identifiers for PHP
==================================

[](#unique-integer-identifiers-for-php)

The goal for this package is:

- To provide unique identifiers.
- The identifiers will be integer so they can be used as primary keys in relational databases to keep performance.
- Do not depend on third services to generate the Ids as happens with workers.
- The generated identifier will be 32 bytes.

The current formula is:

UniqueId = `php-object-identifier` + `random-integer` + `microtime`

To this identifier gets repeated it should coincide the object identifier, the microtime, and a 7 number random integer. That is really very improbable but may happen in very rare ocasion.

Example of use:

```
