如何解决：解析错误：语法错误，文件意外结束，期望函数（T_FUNCTION）或const（T_CONST）

Question

我试图从WordPress网站上的单个产品页面上删除侧边栏。我添加了代码：

`function disable_woo_commerce_sidebar（）{     remove_action（'woocommerce_sidebar'，'woocommerce_get_sidebar'，10）; } add_action（'init'，'disable_woo_commerce_sidebar'）;

到文件末尾，但它没有起作用，所以我删除了它（代码）。但是我可能删除了太多代码并崩溃了吗？文件的其余部分。我是新来的，我想尝试学习。我确定问题出在我如何结束文件/代码
