I was trying to determine how to get a var_dump of constants that are within an interface. Thats right, not using any classes but the interface itself.
Along my travels I found it quite interesting that the ReflectionClass along with a direct call to the interface will also dump its constants. Perfect!!!!
This was using PHP 5.3.1 and my example as below:-
1st File:
constants.php
<?php
<?php>
interface MyConstants
{
// --------------------------
// Programmatic Level
// --------------------------
const DEBUG_MODE_ACTIVE = FALSE;
const PHP_VERSION_REQUIREMENT = "5.1.2";
}
?>
=======
Second file:
=======
test.php
<?php>
include_once ("constants.php");
$oClass = new ReflectionClass ('MyConstants');
$array = $oClass->getConstants ();
var_dump ($array);
unset ($oClass);
?>
what you would get from the command line:-
?:\???\htdocs\????>php test.php
array(2) {
["DEBUG_MODE_ACTIVE"]=> bool(false)
["PHP_VERSION_REQUIREMENT"]=> string(5) "5.1.2"
But as you can see this can work quite well to your advantage in many ways so I truely hope this helps someone else with a similar headache in the future to come!
Enjoy!
