Git terms
Version control is time travel for your codebase
Git is the version control system the entire industry converged on — and there is more to it than commit, push, and pull. This category covers branching strategies, rebasing, merging, conflict resolution, hooks, tags, and the internal object model that explains why Git behaves the way it does. Understanding Git deeply prevents disasters and enables confident collaboration.
Git Rebase vs Merge
Merge preserves branch history with a merge commit — rebase rewrites commits onto the target branch for a linear history.

Git Revert vs Reset vs Restore Three different ways to undo in git — revert creates a new undo commit (safe for shared branches), reset moves HEAD (rewrites history, dangerous on shared branches), restore undoes working directory changes.

Git Submodules & Monorepo Alternatives
Git submodules embed one repo inside another — complex to manage. Composer packages, git subtrees, and monorepos are better alternatives for most PHP projects.

Git Hooks
Scripts that run automatically at specific points in the git workflow — pre-commit for linting, pre-push for tests, commit-msg for message format enforcement.

Git Internals Git stores all data as content-addressed objects (blobs, trees, commits, tags) in a directed acyclic graph — understanding this explains every git command's behaviour.

Git Reflog A log of every position HEAD has pointed to — the safety net for recovering commits after a bad reset, rebase, or accidental branch deletion.

Git Tags Named references to specific commits, used to mark release points — annotated tags include metadata and are signed; lightweight tags are just pointers.
