what is use of “@” in php

@ is error controller operator in php.if we add this operator before any expression or function then any error generated by that expression or function will be ignored.

eg :

(1)include(‘a.php’);

Warning: include(a.php) [function.include]: failed to open stream: No such file or directory

(2)@include(‘a.php’);

no error or warning
