PHP中导出的反射类的格式？

Question

PHP的Reflection层次结构中的每个对象都有一个静态导出方法。您可以使用它来获取类的字符串表示形式。代码类似

$c = new ReflectionClass('Mage_Core_Model_Abstract');
ReflectionClass::export($c)

将回复以下内容

Class [ <internal:Reflection> class ReflectionClass implements Reflector ] {

  - Constants [3] {
    Constant [ integer IS_IMPLICIT_ABSTRACT ] { 16 }
    Constant [ integer IS_EXPLICIT_ABSTRACT ] { 32 }
    Constant [ integer IS_FINAL ] { 64 }
  }

  - Static properties [0] {
  }

这种格式是什么？如果只是内部PHP团队开发的任意内容，或者这是一种可以被其他众所周知的编程工具解析的已知格式？

为了澄清，我知道反射是什么以及如何使用它。我很好奇的是这种“导出”格式，它看起来是故意设计但不是有效的PHP。它是某种标准的CS /编程格式，还是只适用于PHP的一种格式？

Answer 1

这种格式表示Zend引擎解析后如何存储类，你说它是无效的PHP是正确的。
