Laravel Framework是否在启动时实例化每个模型类？

Question

With , where , hasMany etc. methods of Eloquent class are not static.

However we call these functions like that:

// Post is a child of Model class.
Post::where(...); // we don't use New keyword.

So, does Laravel Framework initiate all Model instances before we call their methods?

Answer 1

In the Eloquent's Model class, you have the below function which handles the static method calls dynamically.

public static function __callStatic($method, $parameters)
{
    return (new static)->$method(...$parameters);
}

As you can see, it creates an instance of the Model class on which a non static method is invoked statically, then invokes that method on the instance.
