@ character before a function call
PhpPhp Problem Overview
What is the difference between these two function calls in PHP?
init_get($somevariable);
@init_get($somevariable);
Php Solutions
Solution 1 - Php
the "@" will silence any php errors your function could raise.
Solution 2 - Php
It silences errors and warnings. See Error Control Operators.
Solution 3 - Php
As already answered the @ will stop the error (if any) from showing up.
In terms of performance this is not recommended.
What php is doing is:
- reading the error display state
- setting the error display to show no errors
- running your function
- setting the error display to it's previous state
If you don't want any errors showing up use error_reporting(0);.
Or just write bug free code :P

All PHP expressions can be called with the "@" prefix, which turns off error reporting for that particular expression.
Solution 5 - Php
As everyone said, it stops the output of errors for that particular function. However, this decreases performance greatly since it has to change the error display setting twice. I would recommend NOT ignoring warnings or errors and fixing the code instead.
