How can conflicting dependencies in PHP packages be resolved when using Composer?

Conflicting dependencies in PHP packages can be resolved by using Composer's ability to update specific packages to compatible versions. This can be done by running the `composer update` command and specifying the package that needs to be updated to resolve the conflict. Additionally, Composer allows for the use of version constraints in the `composer.json` file to ensure that compatible versions of packages are installed.

composer update vendor/package
