make:migration - Lyger PHP Framework

The make:migration command generates a new migration file in the database/migrations directory.

Syntax

php rawr make:migration <name>

string

required

Descriptive name for the migration (use snake_case)

Basic Usage

Create a new migration:

php rawr make:migration create_users_table

Output:

Migration created: database/migrations/2026_03_08_143022_create_users_table.php

Migration filenames are automatically prefixed with a timestamp to ensure they run in the correct order.

Generated Migration

The command creates a migration class with up() and down() methods:

database/migrations/2026_03_08_143022_create_users_table.php

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class CreateUsersTable extends Migration
{
    public function up(): void
    {
        $this->getSchema()->create('create_users_table', function ($table) {
            $table->id();
        });
    }

    public function down(): void
    {
        $this->getSchema()->drop('create_users_table');
    }
}

Migration Structure

Class Name

The class name is automatically generated from your migration name:

Migration Name	Generated Class Name
`create_users_table`	`CreateUsersTable`
`add_role_to_users`	`AddRoleToUsers`
`update_products_table`	`UpdateProductsTable`

rawr (line 288)

$className = str_replace(['-', '_'], '', ucwords($name, '-_'));

Timestamp Prefix

Each migration gets a unique timestamp:

rawr (line 284)

$timestamp = date('Y_m_d_His');
$filename = $timestamp . '_' . $name . '.php';

Example: 2026_03_08_143022_create_users_table.php

up() Method

Defines the changes to apply:

public function up(): void
{
    $this->getSchema()->create('users', function ($table) {
        $table->id();
        $table->string('name');
        $table->string('email')->unique();
        $table->timestamp('created_at')->nullable();
    });
}

down() Method

Defines how to reverse the changes:

public function down(): void
{
    $this->getSchema()->drop('users');
}

Naming Conventions

Table Creation

For creating new tables:

php rawr make:migration create_products_table
php rawr make:migration create_orders_table

Column Addition

For adding columns to existing tables:

php rawr make:migration add_status_to_orders
php rawr make:migration add_price_and_stock_to_products

Column Modification

For modifying existing columns:

php rawr make:migration update_users_email_nullable
php rawr make:migration change_price_to_decimal_in_products

Table Deletion

For dropping tables:

php rawr make:migration drop_old_logs_table
php rawr make:migration remove_deprecated_tables

Use descriptive names that clearly indicate what the migration does. This makes it easier to understand your database history.

Common Migration Patterns

Create Table with Columns

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class CreateProductsTable extends Migration
{
    public function up(): void
    {
        $this->getSchema()->create('products', function ($table) {
            $table->id();
            $table->string('name');
            $table->text('description')->nullable();
            $table->decimal('price', 10, 2);
            $table->integer('stock')->default(0);
            $table->boolean('active')->default(true);
            $table->timestamps();
        });
    }

    public function down(): void
    {
        $this->getSchema()->drop('products');
    }
}

Add Columns to Existing Table

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class AddCategoryToProducts extends Migration
{
    public function up(): void
    {
        $this->getSchema()->table('products', function ($table) {
            $table->foreignId('category_id')->nullable()->constrained();
            $table->string('sku')->unique();
        });
    }

    public function down(): void
    {
        $this->getSchema()->table('products', function ($table) {
            $table->dropForeign(['category_id']);
            $table->dropColumn(['category_id', 'sku']);
        });
    }
}

Create Pivot Table

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class CreateOrderProductTable extends Migration
{
    public function up(): void
    {
        $this->getSchema()->create('order_product', function ($table) {
            $table->id();
            $table->foreignId('order_id')->constrained()->onDelete('cascade');
            $table->foreignId('product_id')->constrained()->onDelete('cascade');
            $table->integer('quantity')->default(1);
            $table->decimal('price', 10, 2);
            $table->timestamps();
        });
    }

    public function down(): void
    {
        $this->getSchema()->drop('order_product');
    }
}

Add Indexes

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class AddIndexesToUsers extends Migration
{
    public function up(): void
    {
        $this->getSchema()->table('users', function ($table) {
            $table->index('email');
            $table->index(['last_name', 'first_name']);
            $table->unique('username');
        });
    }

    public function down(): void
    {
        $this->getSchema()->table('users', function ($table) {
            $table->dropIndex(['email']);
            $table->dropIndex(['last_name', 'first_name']);
            $table->dropUnique(['username']);
        });
    }
}

Modify Columns

<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class UpdateUsersEmailNullable extends Migration
{
    public function up(): void
    {
        $this->getSchema()->table('users', function ($table) {
            $table->string('email')->nullable()->change();
            $table->string('phone', 20)->after('email');
        });
    }

    public function down(): void
    {
        $this->getSchema()->table('users', function ($table) {
            $table->string('email')->nullable(false)->change();
            $table->dropColumn('phone');
        });
    }
}

Available Column Types

The schema builder supports various column types:

Numeric

$table->id();                           // Auto-incrementing primary key
$table->integer('votes');               // INTEGER
$table->bigInteger('votes');            // BIGINT
$table->decimal('amount', 8, 2);        // DECIMAL with precision
$table->float('amount', 8, 2);          // FLOAT
$table->double('amount', 8, 2);         // DOUBLE

String

$table->string('name');                 // VARCHAR(255)
$table->string('name', 100);            // VARCHAR(100)
$table->text('description');            // TEXT
$table->char('code', 10);               // CHAR(10)

Date/Time

$table->date('birth_date');             // DATE
$table->dateTime('created_at');         // DATETIME
$table->timestamp('updated_at');        // TIMESTAMP
$table->timestamps();                   // created_at + updated_at
$table->time('sunset');                 // TIME

Other

$table->boolean('active');              // BOOLEAN
$table->json('options');                // JSON
$table->binary('data');                 // BLOB
$table->enum('status', ['pending', 'active', 'inactive']);

Column Modifiers

Customize columns with modifiers:

$table->string('email')->unique();                  // Unique constraint
$table->string('name')->nullable();                 // Allow NULL
$table->integer('votes')->default(0);               // Default value
$table->string('role')->default('user');            // String default
$table->timestamp('created_at')->useCurrent();      // Current timestamp
$table->string('bio')->after('email');              // Column order
$table->text('description')->comment('User bio');   // Add comment

Foreign Keys

Define relationships between tables:

// Simple foreign key
$table->foreignId('user_id')->constrained();

// Custom foreign key
$table->foreignId('author_id')
      ->constrained('users')
      ->onDelete('cascade')
      ->onUpdate('cascade');

// Drop foreign key
$table->dropForeign(['user_id']);

Error Handling

Missing Name

php rawr make:migration

Output:

Error: Migration name required

Directory Creation

The command automatically creates the migrations directory if it doesn’t exist:

rawr (lines 279-282)

$migrationsPath = $basePath . '/database/migrations';
if (!is_dir($migrationsPath)) {
    mkdir($migrationsPath, 0755, true);
}

Source Code

The migration generation logic:

rawr (lines 272-315)

function makeMigration(string $basePath, ?string $name): void
{
    if ($name === null) {
        echo "Error: Migration name required\n";
        exit(1);
    }

    $migrationsPath = $basePath . '/database/migrations';
    if (!is_dir($migrationsPath)) {
        mkdir($migrationsPath, 0755, true);
    }

    $timestamp = date('Y_m_d_His');
    $filename = $timestamp . '_' . $name . '.php';
    $migrationPath = $migrationsPath . '/' . $filename;

    $className = str_replace(['-', '_'], '', ucwords($name, '-_'));

    $content = <<<PHP
<?php

declare(strict_types=1);

use Lyger\Database\Migration;

class {$className} extends Migration
{
    public function up(): void
    {
        \$this->getSchema()->create('{$name}', function (\$table) {
            \$table->id();
        });
    }

    public function down(): void
    {
        \$this->getSchema()->drop('{$name}');
    }
}
PHP;

    file_put_contents($migrationPath, $content);
    echo "Migration created: database/migrations/{$filename}\n";
}

Workflow Example

php rawr make:migration create_posts_table

// database/migrations/2026_03_08_143022_create_posts_table.php
public function up(): void
{
    $this->getSchema()->create('posts', function ($table) {
        $table->id();
        $table->foreignId('user_id')->constrained()->onDelete('cascade');
        $table->string('title');
        $table->text('content');
        $table->string('status')->default('draft');
        $table->timestamp('published_at')->nullable();
        $table->timestamps();
    });
}

Best Practices

Do:

Use descriptive migration names
Always define both up() and down() methods
Keep migrations small and focused
Test rollbacks to ensure they work

Don’t:

Modify existing migrations after they’ve been run
Delete migration files
Put business logic in migrations
Use raw SQL unless absolutely necessary
