Default The @ symbol

What does the @ symbol mean when it is used before a funtion just as:

That supresses error messages from being displayed for that operation should any occur.

Very dangerous to use, BTW, because you won't know what problems would be happening. Always capture it to a variable; for example:
PHP Code:
$result = @mysql_query("whatever");
if (!
$resultweAllDieInFlames("now!");
