LF一个PHP函数，用于根据产品名称在WooCommerce中创建新产品或现有产品的变体

如何解决LF一个PHP函数，用于根据产品名称在WooCommerce中创建新产品或现有产品的变体

在开始之前，请注意，我是一名初级开发人员，从技术上讲，这是我的第一个重要任务。

上下文：母公司提供了超过15,000种产品。子公司从自己的网站中选择15k的固定金额进行销售。各种产品具有相同的产品名称，但大小，颜色等不同。

我正在尝试执行的功能会检查所选产品是否存在重复的产品名称，如果找不到则仅导入或创建这些名称。如果确实找到重复的产品名称，则会在创建新产品的同时创建该产品的变体。

简而言之：寻找PHP函数以创建父产品或父产品+找到相同名称的产品时的变体。

下面是我到目前为止获得的代码，我知道fnmatch可能无法正常工作。 （这是一个API.php文件的片段）

谢谢！
