Here is a code snippet for some of us who are just beginning with reflection. I have a simple class below with two properties and two methods. We will use reflection classes to populate the properties dynamically and then print them:

<?php

class A
{
public
$one = '';
public
$two = '';

//Constructor
public function __construct()
{
//Constructor
}

//print variable one
public function echoOne()
{
echo
$this->one."\n";
}

//print variable two
public function echoTwo()
{
echo
$this->two."\n";
}
}

//Instantiate the object
$a = new A();

//Instantiate the reflection object
$reflector = new ReflectionClass('A');

//Now get all the properties from class A in to $properties array
$properties = $reflector->getProperties();

$i =1;
//Now go through the $properties array and populate each property
foreach($properties as $property)
{
//Populating properties
$a->{$property->getName()}=$i;
//Invoking the method to print what was populated
$a->{"echo".ucfirst($property->getName())}()."\n";

$i++;
}

?>
