What it is

ramsey/uuid is a PHP code library that creates and handles UUIDs, which are long random-looking identifiers used to tag records or objects so they stay unique across systems. Developers add it to a PHP project to generate these IDs instead of writing that logic themselves. The README says it was inspired by the Java and Python UUID libraries.

  • Generate a new UUID for a database primary key in a PHP application
  • Create identifiers for objects passed between services
  • Work with existing UUID strings in a PHP codebase

Great for

  • PHP developers who need unique IDs for database records or API objects
  • Projects that already use Composer to manage PHP dependencies
  • Teams looking for a long-established, MIT-licensed UUID library

Not ideal for

  • People who do not write PHP code, since it is a library rather than a standalone app
  • Projects that need a different language's UUID tooling, since this is PHP only

Strengths

  • MIT license, permissive for commercial and personal use
  • Installs through Composer, the standard PHP package manager
  • Documentation site with examples and an upgrade guide from version 3 to 4

Trade-offs

  • Only usable from PHP; the README does not describe other language ports
  • The README is short, so detailed API behavior has to be checked in the external documentation
  • Upgrading from version 3 requires following a separate migration guide
