结合使用switch_to_blog(), activate_plugins(), 和deactivate_plugins().

您可以将其放入函数中。php，但您希望在它运行后将其删除：

// hook to admin init
add_action(\'admin_init\', \'wpse_swap_plugins\');
function wpse_swap_plugins() {
    // set blog ID per your needs
    $blog_id = 3;
    // switch to the site where you want to activate/deactivate plugins
    switch_to_blog($blog_id);
    // activate: set your path, don\'t set redirect,
    // don\'t make this network wide, don\'t prevent activation hooks
    activate_plugins(array(
        \'/full/path/to/plugin/you/want/to/activate.php\'
    ), \'\', false, false);
    // deactivate: same arguments as activate
    deactivate_plugins(array(
        \'/full/path/to/plugin/to/deactivate.php\'
    ), \'\', false, false);
    // switch context back to original site
    restore_current_blog();
}
