Is there any difference the 2 ways of defining constants?

Hi,
is there any difference between

define ("msgstr", $POST["msgstr"])
and
$msgstr = $POST["msgstr"] ?

Besides using msgstr and $msgstr when referencing it.

Yes; the first one declares a constant, which may not be altered after it is defined; the second one declares a variable, which may be.
