Laravel migration inheritance is not working - php

Question

I'm new to Laravel and php so I face and error I don't know how to solve.
The basic problem is since a lot of tables have primary:id and created_by,updated_by columns what I've figured out is inheriting them in my migrations.
I'm using php7
So I have a Base class
class BaseMigration extends Migration {
public function up(string $tableName) {
Schema::create($tableName, function (Blueprint $table) {
$table->mediumIncrements('id');
$table->primary('id');
$table->unsignedMediumInteger('created_by')->references('id')->on('users');
$table->unsignedMediumInteger('updated_by')->references('id')->on('users');
});
}
}
and the extending migration
class CreateItemsTable extends BaseMigration {
public function up() {
parent::up('items');
Schema::create('items', function (Blueprint $table) {
$table->string('name', 74);
$table->timestamps();
});
}
// ......
}
However php artisan migrate gives me this:
[ErrorException] Declaration of CreateItemsTable::up() should be compatible with Illuminate\Database\Migrations\BaseMigration::up(string $tableName)
Is it because I'm running double up() ?
What am I missing? Appreciate your kind help.

I think you need to have the same function signature, so pass string $tableName:
class CreateItemsTable extends BaseMigration {
public function up(string $tableName) {
Schema::create('items', function (Blueprint $table) {
parent::up('items');
$table->string('name', 74);
$table->timestamps();
});
}
// ......
}
