PHP pre-add at match @ Function Parse _php instance

Everyone in the PHP project, there are always some lines of code with the @ symbol, you know what it means? below to share in PHP the function of the pre-plus at in accordance with the role of @ Resolution

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

Copy the Code code as follows:
@ $page =$_get[' page ']?intval ($_get[' page '): 1;

This is the value from the URL to get the page keyword, such as "Index.php?page=5", then the $page will be taken to 5.

But if there is an error, such as "index.php" After the page keyword, if you go to fetch $_get[' page ' does not exist will be an error, then there is @ can ignore this small error.

Another example:
Copy the Code code as follows:
$conn = Mysqli_conncet ("Q", "W", "E", "R");

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

Copy the Code code as follows:
@ $conn = Mysqli_conncet ("Q", "W", "E", "R");

If the $conn is preceded by the @, you can not let him output the error message.

Here's a little bit of a note.

The above is the PHP pre-plus at in accordance with the role of @ resolution, I hope you like.
