我正在学习laracast教程，但是我的tinker看起来一点也不像laracast，也不会做我想让它做的事情
Psy Shell v0.5.1 (PHP 5.5.12 ÔÇö cli) by Justin Hileman
>>> $article = AppArticle::create{['title' => 'New Article', 'body' => 'New body', 'published_at' => CarbonCarbon::now()]);
PHP Parse error: Syntax error, unexpected '{' on line 1
>>> $article = AppArticle::create{['title' => 'New Article', 'body' => 'New body', 'published_at' => CarbonCarbon::now()]);

>>> $name
PHP error: Undefined variable: name on line 1

>>> $article

这就是它所显示的有人知道什么可能是错的吗?
编辑:新的错误，不能让我继续
$article->save();

你的例子来自Windows命令提示符
你必须记住，Laravel是在美国创建的，那里(几乎)所有的技术人员都是苹果人。如果你不使用Mac，你就不酷;)
所以让我们忘记苹果控制台，从Windows的角度来看。
<>之前>>> $article = new App article=> AppArticle {#658}之前AppArticle{#658}表示tinker准备了一个带有#658 id的空对象。
苹果孵化的Tinker，显示如下:
<>之前>>文章美元;对象(应用程序文章)('increment ' => true;'timestamp ' => true;'exists' => false）之前命令提示符不自动填充对象，它保持为空。
可能的原因是(但这只是我的猜测)，递增的时间戳无论如何都是自动完成的，所以为什么要麻烦呢?
但是这些值，如OSX Tinker所示，是存在的。
如果您希望看到它们，请在命令提示符中运行:
<>之前>> var_dump ($);之前…但请准备好迎接大量的数据。
如果您检查该数据，您将发现缺少对象元素-就像我所做的那样:
<>之前["增加"]=> bool(真正的)("时间戳")=> bool(真正的)["存在"]=> bool(假)之前所以，缺少的对象元素在那里，它们不会显示在命令提示符中。
现在，开始填充新创建的对象:
<>之前>>> $article->title = '新标题';=> "新标题">>> $article->body = 'Some body…哇! ';=>"有人……哇!"之前…你会看到你的对象突然活了起来:
<>之前>>>文章美元=> AppArticle {#659标题:"新标题";某人:"某人……哇!"}之前你也可以把它看作一个数组:
<>之前>>>文章-> toArray ();=> ["title" => "New title"，"body" => "Some body…"哇!"]之前所以，正如你所看到的，它是相同的东西，只是在不同的包装。
问题是，当你学习的时候，每一件小事都会让你恼火，让你偏离正轨。所以，保持冷静，坚持下去——Laravel是非常值得的。即使它只是重新发明同一个轮子……第n次了。但它做得很好。
我重新创建了您提到的错误。问题可能出在迁移文件中。在up()和down()方法中都应该使用
模式:创建("文章"…
和
模式:下降("文章"…
。如果你用"article"来代替，你就会遇到上述错误。请记住，表是为许多文章，所以它的名字是"文章"，而模型描述一篇文章-这就是为什么它的名字是"文章"-但它仍然读取/写入记录从/到"文章"表。
