1. What are Laravel Migrations?
Laravel Migrations are fundamental to manage database changes in Laravel applications. They offer an organized approach to synchronize your database with your application’s codebase across various environments. Imagine your application evolving over time, requiring changes to the database structure or the addition of new tables and data types. Migrations prevent this process from becoming a manual, error-prone ordeal. Each migration file is timestamped, ensuring a clear history of changes executed in the order they were created. This simplifies tasks like rolling back to previous states or applying changes incrementally.

Dependency Management:
Collaboration:
3. How to Implement Laravel Migration?
Step 1: Create a Migration
In Laravel, you can create a migration using the make:migration
Artisan command. Open your terminal and navigate to your Laravel project directory. Then, run the following command:
php artisan make:migration create_example_table
This command will create a new migration file in the database/migrations directory with a name like 2023_09_18_000000_create_example_table.php
. The timestamp in the filename ensures that migrations are executed in the order they were created.

Step 2: Define the Schema
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateExampleTable extends Migration
{
public function up()
{
Schema::create('example', function (Blueprint $table) {
$table->id(); // Auto-incremental primary key
$table->string('name'); // A string column
$table->text('description')->nullable(); // A text column (nullable)
$table->timestamps(); // Created_at and updated_at timestamps
});
}
public function down()
{
Schema::dropIfExists('example');
}}
Step 3: Adding Columns in Table
php artisan make:migration add_new_column_to_example_table --table=example
Open the newly created migration file
(e.g., 2023_09_18_123456_add_new_column_to_example_table.php
) and modify the up and down methods as follows:
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class Add New Column To Example Table extends Migration
{
public function up()
{
Schema::table('example', function (Blueprint $table) {
$table->string('new_column')->nullable(); // Adding a new column
}
public function down()
{
Schema::table('example', function (Blueprint $table) {
$table->dropColumn('new_column'); // Dropping the added column
});
}}
Step 4: Running the Migration
php artisan migrate

4. Other Migration Commands
Adding To Index:
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
Schema::table('users', function (Blueprint $table) {
$table->index('email');
}
Renaming Index:
renameIndex():
$table->renameIndex('email', 'mobile_no');
}
Removing Index:
dropIndex():
$table->dropIndex('email');
}
Using Foreign Key Constraints:
{$table->foreignId('id')
constrained('users')
cascadeOnUpdate()
cascadeOnDelete();}
