  1. get_bloginfo function supports two filters but only if second argument “filter” is set to “display” i.e. 

    get_bloginfo('name', 'display');

    So if you wish to use this for some plugin, it will not be of much use.

    Filters that can be used:

    • bloginfo_url (this one is for all options that return urls)
    • bloginfo

    Usage:

    add_filter('bloginfo_url', 'custom_get_bloginfo', 10, 2);
add_filter('bloginfo', 'custom_get_bloginfo', 10, 2);

function custom_get_bloginfo($output, $show) {
    switch( $show ) {
        case 'description':
            $output = 'my custom description';
            break;
        case 'name':
            $output = 'custom name';
            break;
    }

    return $output;
}

    UPDATE:
    If you just wish to replace site description you can do this:

    add_filter('option_blogdescription', 'custom_option_description', 10, 1);
function custom_option_description($value) {
    return 'custom description';
}

  2. Ok I understand it now, the better way to do it is to edit your header.php and look for bloginfo( ‘description’ ) then change it with custom_get_bloginfo() then add you can use this to your function.php

    function custom_get_bloginfo(){
switch( $show ) {
case 'description':
$output = "my description";
break;

default:
$output = get_option('blogname');
break; 
}
return $output;
}
