如何打印定义的常量数组？

Question

I think that I have an easy questions, but I'm unable to find what I'm looking wrong!!

I've an array where there are some strings:

$tipus_membre = array("lider","colider","vetera","membre");

and this strings are defined:

define("LIDER","Leader");
define("COLIDER","Co-leader");
define("VETERA","Elder");
define("MEMBRE","Member");

I'm trying to print in a form but i'm unable to get it. With this first option i get only the name "lider", "colider"....:

<select name="cla_tipus" required>
<?php
for($i=0;$i<count($tipus_clan);$i++){
    echo '<option value="'.$i.'">'.$tipus_membre[$i].'</option>';
}
?>
 </select> 

and if i put:
constant($tipus_clan[$i]);

I get nothing.

(Edited the $var)

Thanks to all for the quick answers, finally the problem was where you said, in the case-sensitive.

The code now it works with a minor change and it's:

<?php
for($i=0;$i<count($tipus_clan);$i++){
    echo '<option value="'.$i.'">'.constant(strtoupper($tipus_membre[$i])).'</option>';
}
?>
