停用wp版本上的插件

我目前正在创建一个主题选项页面，并正在使用此功能deactivate_plugins() 我正在运行wordpress 3.8.3，所以在插件中运行此代码应该可以卸载它。

问题

1、我是否错误地使用了此功能？2、由于Wordpress的4.0版本不存在，逻辑不起作用吗？

 register_activation_hook( __FILE__, \'dw_deactivate_theme_options\' ); // activate hook

    function dw_deactivate_theme_options() {
        if ( version_compare( get_bloginfo(\'version\'), \'4.0\', \'<\') )  { // check the version
            deactivate_plugins( basename( __FILE__ ) ); // deactivate this plugin if the version is lower then 3.8
        }
    }
