PHP:通过 ClassName::method 语法调用实例方法，导致静态调用? [英] PHP: call to an instance method via ClassName::method syntax, results in a static call?

问题描述

她是我的代码:

class MyClass 
{
   public $prop;
   public function method ()
   {
     echo $this->prop;
   }
}

然后在代码中的某个地方，意外地:

Then somewhere in the code, accidently:

MyClass::method();

我希望对上述行有一个解释错误，因为被调用的方法不是静态的.相反，该方法被调用，我收到了一个关于 $prop 不存在的异常.所以我知道该方法被称为静态方法，即使它不是.

I would expect to have an interpretation error about the above line, because the called method is not static. Instead, the method was called, and I received an exception about $prop not existing. So i understand that the method was called as a static method, even though it's not.

它是这样工作的吗?(为什么?)

Does it work this way? (Why the hell? )

推荐答案

静态调用非静态方法会生成 E_STRICT 级别警告.

Calling non-static methods statically generates an E_STRICT level warning.

我想您已经抑制了 E_STRICT 警告.它有效(可能是由于遗留原因)，但不推荐这样做.

I suppose you have E_STRICT warnings suppressed. It works (likely for legacy reasons), but it's not recommended.
