Status: Open
Bug Type: Misbehaving function
Description: no warning when trying to overwrite define/no undefine!?
1)
when trying something like this:
error_reporting(63);
define("CONSTANT", "Hello dfdfdffd.");
define("CONSTANT", "Hello world.");
it would be nice to get a warning when the second define takes no effect.
2)
in the doc-file (.../lang-const.html#CONSTANTS, Date: 1998-12-28, Release: 3.0.7-dev) I found:
<?php
define("CONSTANT", "Hello world.");
echo CONSTANT; // outputs "Hello world."
undefine ("CONSTANT");
?>
but i results in:
Hello world.<br>
<b>Fatal error</b>: Call to unsupported or undefined function undefine() in <b>...</b> on line <b>...</b><br>
and in the actuell doc-file I miss it!?
3)
is it possible to test a constant wether it is set like:
define("CONSTANT", "Hello world.");
if(isset(CONSTANT))
......
