Composer The Right Way
7 likes1,490 views
The document discusses the usage of Composer, a dependency manager for PHP, highlighting common issues such as problems with package resolution and installation failures. It also provides guidance on managing dependencies, using semantic versioning, and best practices for library publishers and consumers. Multiple examples are given for successfully requiring and managing packages, along with troubleshooting tips and installation commands.
