Why do I get duplicate define although using require_once()?
<p>My defs.php has a define that I need, and although I used require_once for it, when I try to access defs.php, I get a series of duplicates as if the defs.php was already called before.
On the other hand, if I don't call it, I get undefined <code>use of undefined constant</code>...</p>

<p>Any ideas? </p>

<p>Thanks!</p>
