PHP has a function for nearly everything:
http://php.net/extract
in this case:
extract($_POST);
Keep in mind that this is barely better than having register_globals ON. It is
sometimes better to set all of the variables you expect from the POST input to
some empty value and use the EXTR_IF_EXISTS flag with extract:
$firstname=$lastname=$email=$comment="";
extract($_POST, EXTR_IF_EXISTS);
Then, if someone tries to add other variables to your application, especially
in an attempt to overwrite key variables you might use for logged in status,
etc., only the variables which are already set will be transformed by extract()
into local variables.
Naturally, extract() should be called at the top of your program to prevent
overwriting values as well.
