Question

Please consider the following example code:

<?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());

?>

That produces the following output:

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

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

Thank you.

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

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