Hi guys..

i'm using the following code

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use laajchaina\User;

class UsersTableSeeder extends Seeder {

	/**
	 * Run the database seeds.
	 *
	 * @return void
	 */
	public function run()
	{
		$faker = Faker\Factory::create();

		$this->command->info('Clearing Users Table');
		User::truncate();

		$this->command->info('Creating User: zxczxc zxczxc');


		$this->command->info('Creating New Users');
		$users = [];												// initialize new users list
		$users = [													// creating a default admin user
			'firstname' 		=> asdasdasd,
			'lastname'			=> asdasdasd,
			'email' 			=> 'asida@asd.com,
			'password' 			=> Hash::make(asdasdasd),
			'created_at'		=> 'NOW()',
			'updated_at'		=> 'NOW()'
		];

		$counter = 0;
		foreach(range(1, 1000) as $index)							// get a list of random users from Faker lib
		{
			$users[] = [
				'firstname' 	=> $faker->firstname,
				'lastname' 		=> $faker->lastname,
				'email' 		=> $faker->email,
				'password'		=> Hash::make('1234'),
				'created_at'	=> 'NOW()',
				'updated_at'	=> 'NOW()'
			];

			++$counter;
			if( $counter > 100 )
			{
				$counter = 0;
				DB::table('users')->insert($users);
				$users = [];
			}
		}

		DB::table('users')->insert($users);
	}
}

I get the following error while seeding with this seeder:

[ErrorException] preg_replace(): Parameter mismatch, pattern is a string while replacement is an array

can anyone help me with this please.
