PHP » Operators » @
- Syntax:
- @expression
- expression
- Statement or expression that might otherwise cause an error or warning message to be printed.
Silence.
The silence operator prevents error and warning messages from being printed.
Examples
Code:
<?php
$a++;
@$b++;
?> Output:
Notice: Undefined variable: a in \samples\operators\silence.php on line 11
Explanation:
Incrementing a variable that has not previously been assigned a value generates a warning. However, since $b++ was prepended with "@", no warning is printed for that line.
