    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++;
    }

    ?>
