Definition:
If you write a program and don’t want any error to show on the screen, then put @ before the expression that creates the error.
You can use this operator inside a function, outside a function, or anywhere an error can happen.
This symbol hides the error message.
Its simple work is to stop the error from showing on the screen.
Syntax:
@expression
Example:
<?php $number = 10; $denominator = 0; $result = @$number / $denominator; echo $result; ?>
Output:
0
In the above example, without @, PHP shows a warning (division by zero). After adding @, it hides the warning and shows 0.
