Answer 1

[27-May-2018 20:37:37 UTC] PHP 已弃用：与其类同名的方法在 PHP 的未来版本中将不再是构造函数；FGMembersite 在第 24 行的 /home/gurudev/public_html/user/include/fg_membersite.php 中有一个已弃用的构造函数

这意味着该类的构造函数以 php 在未来版本中不再支持的方式命名。

class FGMembersite{

    public function FGMemmbersite() : void{
        echo "something";
    }
}

class FGMembersite{

    public function __construct() : void{
        echo "something";
    }
}

new FGMembersite();

这两个类都会回显“某事”，不同之处在于第一个构造函数方法在未来的 php 版本中将不再工作，因为它与类本身同名；它必须是 __construct()

它警告你，你的代码可能会破坏这条线。
