What are some potential pitfalls or challenges when using Composer in PHP projects, such as handling different versions or dependencies?

One potential challenge when using Composer in PHP projects is handling different versions of dependencies. This can lead to compatibility issues or conflicts between packages. To solve this, it's important to define specific version constraints for each dependency in the composer.json file.

{
    "require": {
        "vendor/package": "^1.0"
    }
}
