I'm comparing the two Scripts 12.1 and 12.2 and notice line 12
if ($dbc = mysqli_connect('localhost', 'username', 'password', 'myblog')) { // Script 12.1
if ($dbc = @mysqli_connect('localhost', 'username', 'password', 'myblog')) { // Script 12.2
What is the use of the '@'?
What is the difference between with and without '@' on @mysqli_connect() and when to use the '@'?
