    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++;
    }

    ?>
