This piece of code is just an example to show the bug : please read NAME and NOM as the same constant. I tested this code and it print _really_ "value". As for the name of an undefined constant being treated as the string value of the name, i didn't knew about it. It just makes me wonder more how are we supposed to check if a constant is defined within a function or a class, and why we can't althought we can access the value of this constant. I can't help but thinking that this _is_ a bug. ------------------------------------------------------------------------ [2002-11-13 07:35:44] tix@php.net Btw. your example is wrong, you check 'NOM' instead of 'NAME'. Another thing in your script is "defined(NOM)". You should write "define('NOM')". And the last: you can't use "if (NAME)" for a replacement of "if (defined('NAME'))". In this case NAME is evaluted to the string 'NAME'. The condition is always TRUE :) Think about it. ------------------------------------------------------------------------ [2002-11-13 07:32:26] cynic@php.net first, read the code you gave us again. it can't produce the output you claim it does. it will output "NOM", and possibly an E_NOTICE. clearly, this is not a test case for your perceived problem. second, i don't know what EasyPHP is, but maybe you should file a PR with its vendor? ------------------------------------------------------------------------ [2002-11-13 07:20:19] fredbird@contactoffice.net I was not asking for support nor help. I know that i can replace "if (defined(NAME))" by "if (NAME)", for example. I may be wrong about the place where i reported this bug. But i wonder how you can explain that this is a good behavior for defined() : how can a constant have a value that you can have access to and not be defined ? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
