Quick Fix needed with functions.php

I am wanting to add this

// Ondemand function to generate dynamic bit.ly urls
function getBitlyUrl($url) {
    // fill up this 2 lines below with your login and api key
    $bitlylogin = 'mylogin';
    $bitlyapikey= 'myapi ';

    // you dont need to change below this line
    $bitlyurl = file_get_contents("http://api.bit.ly/shorten?version=2.0.1&longUrl=".$url."&login=".$bitlylogin."&apiKey=".$bitlyapikey);  

    $bitlycontent = json_decode($bitlyurl,true);

    $bitlyerror = $bitlycontent["errorCode"];

    if ($bitlyerror == 0){
        $bitlyurl = $bitlycontent["results"][$url]["shortUrl"];
    }
    else $bitlyurl = $url;

    return $bitlyurl;
}	

Code (markup):

To my functions.php file which contains this -

<?php
require_once(TEMPLATEPATH . '/controlpanel.php'); 
if ( function_exists('register_sidebars') )
    register_sidebars(2);
	 
		register_sidebar(array('name'=>'Sidebar 3',
		'before_widget' => '',
		'after_widget' => '</li></ul></div>',
		'before_title' => '<div class="sidebar3"><h2>',
		'after_title' => '</h2><ul><li>',
	)); 
	 
?>

PHP:

But anywhere I add it, my admin panel messes up when I activate a plugin or empty my cache. Any help on exactly where in this file I should place this would help. Thanks!

 

Did you add it like this and it didn't work? What error showed?

<?php
require_once(TEMPLATEPATH . '/controlpanel.php'); 
if ( function_exists('register_sidebars') )
    register_sidebars(2);
     
        register_sidebar(array('name'=>'Sidebar 3',
        'before_widget' => '',
        'after_widget' => '</li></ul></div>',
        'before_title' => '<div class="sidebar3"><h2>',
        'after_title' => '</h2><ul><li>',
    )); 

// Ondemand function to generate dynamic bit.ly urls
function getBitlyUrl($url) {
    // fill up this 2 lines below with your login and api key
    $bitlylogin = 'mylogin';
    $bitlyapikey= 'myapi ';

    // you dont need to change below this line
    $bitlyurl = file_get_contents("http://api.bit.ly/shorten?version=2.0.1&longUrl=".$url."&login=".$bitlylogin."&apiKey=".$bitlyapikey);  

    $bitlycontent = json_decode($bitlyurl,true);

    $bitlyerror = $bitlycontent["errorCode"];

    if ($bitlyerror == 0){
        $bitlyurl = $bitlycontent["results"][$url]["shortUrl"];
    }
    else $bitlyurl = $url;

    return $bitlyurl;
}     
?>
