Hello Parham,
I know what the @ operator does (it stops PHP from reporting errors
and makes it ignore error_reporting() or any INI directives) but I
don't understand why to use it here, with mysql_query() function.

Subject: MySQL query not working!
Andre,
The @ operator is used for error catching statements. When you put:
@mysql_connect('localhost', 'username', 'password') or die('Could not
connect.');
If PHP fails to make a connection, the script execution is stopped, and the
error message between the apostrophes is given.
And, I found out what the problem was; I should have put:
if (mysql_num_rows($result))
rather than just
if ($result)
Thanks!
