An example of the PHP @ at Mark's role is to introduce _php tips

Look at the PHP code, there are always some lines in front of the @ symbol, always do not know what it means. For example dede5.7 @ni =imagecreatetruecolor (Ftow, $ftoH);

If you use it today, just remember it. In fact, it is the error control character, that is, even if an error occurred, but also ignore the error message, continue to execute the code below.

@ $page =$_get[' page ']?intval ($_get[' page ']): 1;

The sentence is to get the value of the page keyword from the URL, such as "index.php?page=5", then the $page will take 5.

However, if there is error, such as "index.php" after no page keyword, if you go to fetch $_get[' page ' does not exist will be an error, then have @ can ignore this small mistake.

Another example:

$conn = Mysqli_conncet ("Q", "W", "E", "R");

This will enter an error message about the connection to the database.

If $conn in front of the @ can not let him output the error message.

@ $conn = Mysqli_conncet ("Q", "W", "E", "R");

Just remember it here.
