The "getconstant" method can be used to get the value associated with a constant
of a particular class that you are examining.
The following code snippet shows this:
<?php
class Test{
const ONE = "Number one";
const TWO = "Number two";
}
$obj = new ReflectionClass( "Test" );
echo $obj->getconstant( "ONE" )."\n";
echo $obj->getconstant( "TWO" )."\n";
?>
output:
Number one
Number two
