Question

I use a code to connect gmail and get my friends list. In that code there is a function call

redirect('https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token='. $oauth->rfc3986_decode($accrss_token['oauth_token']), 'location');

I’ve searched for function redirect() but didn’t find it in the php manual. Is it a built in function in php?

The 2nd parameter is 'location' what is the use of that parameter?

Here is the function where it’s used:

public function connect_google($oauth=null){

if(!$oauth)
{
    return null;
}
//create a gmailcontacts objects
$getcontact = new GmailGetContacts();
$accrss_token = $getcontact->get_request_token($oauth, false, true, true);

$this->ci->session->set_userdata('oauth_token', $accrss_token['oauth_token']);
$this->ci->session->set_userdata('oauth_token_secret', $accrss_token['oauth_token_secret']);
//redirect to google auth
redirect('https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token='. $oauth->rfc3986_decode($accrss_token['oauth_token']), 'location');

}

It is part of the CodeIgniter URL helper. See:

http://codeigniter.com/user_guide/helpers/url_helper.html

From the documentation:

Does a “header redirect” to the URI specified. If you specify the full site URL that link will be build, but for local links simply providing the URI segments to the controller you want to direct to will create the link. The function will build the URL based on your config file values.
