如何修复“调用未定义函数”-PHP、mgp25

Question

首先，我检查了几十个搜索结果，包括几篇关于此主题的 StackOverflow 文章 - 不，似乎没有人回答过它（尽管问题本身可能看起来类似于你）

总结问题：在类外调用公共函数/调用方法时，出现如下错误：'Call to undefined function...'

}

getInfoByName("testuser")
//echo setCloseFriends(["Versaute.Witze", "Instagram"], ["leonie.kai"]);

//$ig->people->setCloseFriends($add = $addinput, $remove = $removeinput, $module = 'favorites_home_list', $source = 'audience_manager');

?>

问题在于“getInfoByName”函数——显然无法调用。 我指的 GitHub 代表是 mgp25/Instagram-API。

您必须初始化一个类的新实例。

(new People($ig))->getInfoByName('testuser')
