序列化 PHP 反射 [英] Serialized PHP Reflection

问题描述

请考虑以下示例代码:

<?php

class a {
    function b() {}
}

$r=new ReflectionMethod(new a, "b");
var_dump($r->getParameters());
$s=serialize($r);
$r=unserialize($s);
var_dump($r->getParameters());

?>

产生以下输出:

array(0) { }
Fatal error: ReflectionFunctionAbstract::getParameters() [<a href='reflectionfunctionabstract.getparameters'>reflectionfunctionabstract.getparameters</a>]: Internal error: Failed to retrieve the reflection object in [...]test.php on line 13

问题是，有没有办法在 PHP 中正确序列化/反序列化 Reflection 对象?

The question stands, is there a way to correctly serialize/unserialize Reflection objects in PHP?

谢谢.

序列化不适用于虚拟属性和这个问题通常发生在内部类中.

Serialization doesn't work on virtual properties and this problem usually occurs with internal classes.

也许这种方法就是这种情况.但是，我不确定文档不清楚.http://in3.php.net/manual/en/reflectionfunctionabstract.getparameters.php

Maybe that is the case with this method. However, I'm not sure the documentation is not clear. http://in3.php.net/manual/en/reflectionfunctionabstract.getparameters.php
