如何在此片段中添加php条件

Question

任何人都可以使用if条件修改以下代码以执行以下操作：

如果名为“uwa_auction_bids_history”的选项卡存在，那么选项卡的重新排序将按原样完成，但如果它不存在，则只需要重新排序的前两个选项卡（“description＆additional_information”）它应该是基本的if /要添加到此片段的其他条件，但我没有PHP知识，所以我需要一个善良的人的帮助...

谢谢！

/**

add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );
function woo_reorder_tabs( $tabs ) {

    $tabs['description']['priority'] = 5;           // Reviews first
    $tabs['additional_information']['priority'] = 10;           // Description second
    $tabs['uwa_auction_bids_history']['priority'] = 15; // Additional information third

    return $tabs;
}

基于Slobodan的帮助，我调整了代码以满足我的需求。感谢Slobodan的帮助！问题解决了！

/**
 * Reorder product data tabs
 */
add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );
function woo_reorder_tabs( $tabs ) {
    if ($tabs[''] !== undefined)
    $tabs['description']['priority'] = 5;           // Description first
    $tabs['additional_information']['priority'] = 10;           // Details second
    {
    $tabs['description']['priority'] = 5;           // Description first
    $tabs['additional_information']['priority'] = 10;           // Details second      $tabs['uwa_auction_bids_history']['priority'] = 15; // Bids third      
    }
    return $tabs;
}
