Remove Yahoo Search from Firefox

Hi Friends,

Yahoo messenger sometimes installs yahoo search in firefox. And when we search something from address bar, it displays yahoo search results. I never want so.. I wanted google back and here it is how to do so..

1. Open about:config in firefox. Just type about:config in address bar.
2. It will ask whether you will be careful or not.. say I'll be careful, I promise!
3. In the search bar search for keyword.url
4. Modify the value to your favorite search engine. I wanted google so I modified the value to
http://www.google.com/search?q=
Now it will be searching google only.. enjoy!!!

[PHP] Error Reporting : Turn off Warnings/Errors/Notices

Hi Friends,

Recently I was writing a simple personal site. I had to add some php script as well to communicate with mysql server. For any error, warning, I used to see messages in browser which can be frustrating at times. If you are looking for a way to disable those messages.. here it is.

We are going to use error_reporting($level) function of php. Syntax is:

int error_reporting ([ int $level ] )

Write this in php file where you want.
<?php

// Turn off all error reporting
error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Report all PHP errors (bitwise 63 may be used in PHP 3)
error_reporting(E_ALL);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

?>

Thats how you do.. Cheers!!!
