## Code

```php
add_action( 'admin_bar_menu', function ( $bar ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        return;
    }

    $bar->add_node( array(
        'id'    => 'wpide-clear-all-caches',
        'title' => esc_html__( 'Clear all caches' ),
        'href'  => wp_nonce_url( add_query_arg( 'action', 'wpide_clear_all_caches', admin_url( 'admin-post.php' ) ), 'wpide_clear_all_caches' ),
    ) );
}, 95 );

add_action( 'admin_post_wpide_clear_all_caches', function () {
    check_admin_referer( 'wpide_clear_all_caches' );

    if ( ! current_user_can( 'manage_options' ) ) {
        wp_die( esc_html__( 'Sorry, you are not allowed to do that.' ), 403 );
    }

    $cleared = array();

    if ( function_exists( 'rocket_clean_domain' ) ) {
        rocket_clean_domain();
        $cleared[] = 'WP Rocket';
    }
    if ( defined( 'LSCWP_V' ) ) {
        do_action( 'litespeed_purge_all' );
        $cleared[] = 'LiteSpeed';
    }
    if ( function_exists( 'w3tc_flush_all' ) ) {
        w3tc_flush_all();
        $cleared[] = 'W3 Total Cache';
    }
    if ( function_exists( 'wp_cache_clear_cache' ) ) {
        wp_cache_clear_cache();
        $cleared[] = 'WP Super Cache';
    }
    if ( isset( $GLOBALS['wp_fastest_cache'] ) && method_exists( $GLOBALS['wp_fastest_cache'], 'deleteCache' ) ) {
        $GLOBALS['wp_fastest_cache']->deleteCache( true );
        $cleared[] = 'WP Fastest Cache';
    }
    if ( function_exists( 'sg_cachepress_purge_cache' ) ) {
        sg_cachepress_purge_cache();
        $cleared[] = 'SG Optimizer';
    }

    wp_cache_flush();
    $cleared[] = 'object cache';

    set_transient( 'wpide_cleared_' . get_current_user_id(), implode( ', ', $cleared ), 60 );
    wp_safe_redirect( wp_get_referer() ? wp_get_referer() : admin_url() );
    exit;
} );

add_action( 'admin_notices', function () {
    $key  = 'wpide_cleared_' . get_current_user_id();
    $done = get_transient( $key );

    if ( $done ) {
        delete_transient( $key );
        echo '<div class="notice notice-success is-dismissible"><p>' . esc_html( sprintf( 'Cleared: %s.', $done ) ) . '</p></div>';
    }
} );
```

## Notes

Handy on agency sites where different clients use different cache plugins. Only administrators see it.
