Using PHP 4.3.4RC1.
It should *really* be noted that if you expect that this function:
<?php
function safeDefine($const, $val)
{
if(!defined($const))
{
define($const, $val);
}
}
?>
will do what you might expect, you are wrong.
I don't know if this is a bug or not, but the function that works for this example is:
<?php
function safeDefine($const, $val)
{
if(defined($const) === FALSE)
{
define($const, $val);
}
}
?>
