I need to check empty data value before insert into database. i have two way:

One:

$comment = (empty($_POST['regcomment'])) ? '0' : $_POST['regcomment']; $sql = update("UPDATE " . OPTIONS . " SET comment = ? ", $comment);

Two :

$sql = update("UPDATE " . OPTIONS . " SET comment = ? ", (empty($_POST['regcomment'])) ? '0' : $_POST['regcomment']);

which way is better?!

This is primarily opinion based. It both leads to the same result, the only difference is that in the second version you do not have the result of the ternary-statement in a variable in case you need it again.

In the first version the ternary-statement and function-call are split, so it's arguably more readable.
