Usage
-----

Example usage may be found in the tests and demo directories.

Note: For convenience you may use the same class names for struct and object 
as Satellite uses, to simplify a migration to Universe.

A very simple example follows here:

<?php
$ior = "IOR:000000000000000f49444c3a52616e646f6d3a312e3000000000000100000000000000500001000000000016706c616e7874792e6473672e63732e7463642e69650006220000002c3a5c706c616e7874792e6473672e63732e7463642e69653a52616e646f6d3a303a3a49523a52616e646f6d00";
$obj = new UniverseObject($ior);
$value = $obj->lrand48();
echo "Random value retrieved: $value\n";
?>


Using enumerations
------------------

Universe does not handle enum:s like Satellite.

The class for enum:s is removed and replaced with the possibility to use
strings as enum values, for example:

// IDL

enum enum_data_type
{
	zero, one, two, three, four, five, six, seven
};

interface DataTypes
{
	enum_data_type loop_enum(in enum_data_type value);
};

// PHP

<?php 

class DataTypes 
{
	function loop_enum($value) { return $value; }
}

$object = new UniverseObject(new DataTypes(), "IDL:DataTypes:1.0");

echo $object->loop_enum(1)."\n";
echo $object->loop_enum(two)."\n";
echo $object->loop_enum("three")."\n";

?>

// Output

one
two
three


Creating CORBA objects in PHP
-----------------------------

See server.php and client.php in the demo directory.
