define htaccess ?

Hypertext Access, commonly shortened to htaccess, is a powerful configuration file which controls the directory it is placed in and all the subdirectories underneath it.

.htaccess is a configuration file for use on web servers running the Apache Web Server software. When a .htaccess file is placed in a directory which is in turn ‘loaded via the Apache Web Server’, then the .htaccess file is detected and executed by the Apache Web Server software.

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
