快速获取Mysql 字段生成ORM的$fillable 属性,顺序和数据库保持一致

使用方式：

代码如下

<?php

namespace App\Console\Commands;

use DB;
use Illuminate\Console\Command;
use Illuminate\Database\Schema\Blueprint;

class GetTableColumns extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'tools:get-table-columns
                            {table : The table name}
                            {con? : The table connection}';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = '获取数据库字段';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return int
     */
    public function handle()
    {
        $table = $this->argument('table');

        $connection = $this->argument('con');

        $con = $connection ?: 'mysql';

        $db = config('database.connections.'.$con.'.database');

        $columns = DB::select('select column_name from information_schema.columns where table_name= ? and TABLE_SCHEMA = ? order by `ordinal_position`', [$table, $db]);

        $columns = array_column($columns, 'COLUMN_NAME');

        $columns = array_diff($columns, ['id', 'created_at', 'updated_at', 'deleted_at']);

        $this->newLine();

        $this->info('protected $fillable = [');

        foreach ($columns as $column) {
            $this->info("    '".$column."',");
        }

        $this->info('];');

        return 0;
    }
}

下面这种方式也能获取字段，但是有个问题是顺序会打乱(不推荐)：
$columns = DB::connection()->getSchemaBuilder()->getColumnListing($table);
