    Quick tip for disabling a plugin at run time using the ‘active_plugins’ option:

    // Outputs an array of all plugins.
     var_dump( get_option( 'active_plugins' ) );
    
     add_filter( 'option_active_plugins', function( $plugins ){
    	if ( $my_condition ) {
    		unset( $plugins['my-plugin-slug'] );
    	}
    	return $plugins;
    });
    
    // Outputs an empty array.
    var_dump( get_option( 'active_plugins' ) );

    Example migrated from Codex:

    For example, to filter the blog description, you may use option_blogdescription.

    In the following sample code, we change the blog description on archive pages to include a page number (i.e. changing to “Example description. Page 2“). This is a common usage scenario to avoid duplicate meta description error in Google Webmaster Tools.

    add_filter( 'option_blogdescription', 'my_theme_filter_blogdescription' );
    
    function my_theme_filter_blogdescription( $description ) {
    
    	if ( ! is_archive() ) {
    		return $description;
    	}
    
    	global $page, $paged;
    
    	if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() ) {
    		$description .= $description . sprintf( __( ' Page %d' ), max( $paged, $page ) );
    	}
    
    	return $description;
    }

    Please note: this filter hook does NOT run when the option does NOT exist in the database. So it can only be used to filter existing options, not to filter the false response when there is no option found. For that, you’ll need the hook default_option_{$option}
