PHP Social-Network Script Exploration (DB Migrations)

Overview

The remnants of work with a PHP “Facebook-style” social-network script. What survives in the archive is the database upgrade path, a series of incremental SQL migration files carrying the schema from v1.0 up to v1.6.

Why It Exists

The developer was setting up / building with a self-hosted social-network (Facebook-clone) PHP product, of the kind sold as turnkey scripts in that era, to study how such a platform is structured.

What We Built

The folder holds database-update-for-old-versions/, a chain of versioned migration scripts (database-v.1.0-to-v.1.1.sql through database-v.1.6.1-to-v.1.6.2.sql) that evolve the social platform’s MySQL schema across releases. The application code itself is not in the archive; the migrations are what remained.

Technologies & Approach

A PHP + MySQL social-networking script, with schema evolution managed through hand-written, version-to-version SQL upgrade files, the typical migration mechanism for packaged PHP products before framework migration tooling was widespread.

Outcome / Impact

A learning/setup exercise around social-platform internals. Honestly partial, only the migration artefacts persist, but it shows exposure to relational schema design and versioned database upgrades.

Capabilities Demonstrated

• Reading and applying versioned SQL schema migrations
• Relational (MySQL) schema evolution across releases
• Standing up a self-hosted social-network platform
