当我尝试迁移我的个人资料 table 时出现错误。我正在使用 laravel 5.1

when i try to migrate my profile table its giving me the error .i am using laravel 5.1

[Symfony\Component\Debug\Exception\FatalErrorException] syntax error, unexpected '(', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

这是我的代码

public function up()
        {
            Schema::create('profile', function (Blueprint $table) {
                $table->('userid')->unsigned()->default(0);
                $table->string('profile')->default('http://localhost/laravel/public/image/uzair.jpg');
                $table->string('about',255);
                $table->foreign('userid')->references('id')->on('users')->onDelete('cascade');
                $table->timestamps();
            });
        }
$table->('userid')

这就是您收到语法错误的原因。应该是$table->integer('userid').
