const integer IS_PUBLIC = 256 ;

const integer IS_PROTECTED = 512 ;

const integer IS_PRIVATE = 1024 ;

/* Propiedades */

public $name ;

public $class ;

/* Métodos */

final private void __clone ( void )

public __construct ( mixed $class , string $name )

public static string export ( mixed $class , string $name [, bool $return ] )

public ReflectionClass getDeclaringClass ( void )

public string getDocComment ( void )

public int getModifiers ( void )

public string getName ( void )

public mixed getValue ( object $object )

public bool isDefault ( void )

public bool isPrivate ( void )

public bool isProtected ( void )

public bool isPublic ( void )

public bool isStatic ( void )

public void setAccessible ( bool $accessible )

public void setValue ( object $object , mixed $value )

public string __toString ( void )

}

Please ignore my previous note. I didn't fully understand what the previous notes were referring to as "runtime". I now see they were referring to a slightly different question.



Apologies!

I think a more accurate explanation is this:



The Reflection classes are designed to reflect upon the source code of an application, not on any runtime information.



I think you misunderstand the ReflectionProperty constructor in your example above. The fact that it accepts an object as argument is just a convenience feature - you are actually inspecting the class of that object, not the object itself, so it's basically equivalent to:



<?php



// works fine 

$Reflection = new ReflectionProperty(get_class($a), 'a');



// throws exception 

$Reflection = new ReflectionProperty(get_class($a), 'foo');



?>



Getting the class of the object you're passing in is implied, since inspecting a defined property is the purpose of this class.



In your example, $a->foo is a dynamic member - it is not defined as a member of class, so there is no defining class reference, line number, default value, etc. - which means, there is nothing to reflect upon.



Clearly this very useful library could use some real documentation...
