ramsey/uuid is a PHP library for generating and working with universally unique identifiers (UUIDs) conforming to RFC 9562 (formerly RFC 4122). It supports all standard UUID versions (1-8), GUIDs, and nonstandard formats, with customization options for codecs, validators, and factories.

Use cases

• generate uuids in php
• create rfc 9562 compliant unique identifiers
• generate uuid v7 for database primary keys
• parse and validate uuid strings in php
• generate name-based md5 or sha1 uuids
• store uuids as bytes or strings in a database
• mock uuids for testing php applications

When to choose

• you need standards-compliant UUID generation in a PHP 8+ project
• you need sortable time-ordered UUIDs (v6/v7) for database keys
• you need to work with GUIDs or nonstandard UUID variants
• you want a mature, widely-used PHP UUID library with active maintenance

When to avoid

• your project is not written in PHP
• you only need simple random IDs and don't require UUID semantics
• you need UUID generation in another language's native runtime without FFI
