Schema-first database migrations for PHP.

Schemage lets you describe the desired database structure with a clean PHP DSL, compare it with the current database, review a migration plan, generate SQL, and apply the required changes through a lightweight CLI.

Features

• Schema-first PHP DSL
• MySQL, MariaDB, and SQLite support
• Database introspection and schema diffing
• Table, column, index, and foreign-key operations
• Explicit table and column renames
• Driver-specific operation planning
• Interactive migration plans
• Dry-run and SQL export modes
• Migration history and rollback support
• Destructive-operation protection
• Optional model generation

Installation

composer require eril/schemage

        $t->id();
        $t->string('name');
        $t->string('email')->unique('users_email_unique');
        $t->timestamps();
    });
