The function defined() always return false within a function or class, although the value of the constant is still available.

the code :

define(NAME, "value");
function f() {
     if (defined(NOM)) echo "NOM is defined";
     echo NOM;

will print "value" only. Currently tested with EasyPHP running with a Windows XP computer.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.
