这些错误是什么意思。这些错误是否与我的托管服务提供商有关？

Answer 1

看起来您可能已经将php.ini 配置文件直接从系统复制到了托管服务器。不要那样做。配置文件中的数据特定于 XAMPP 安装；这不适用于 Web 服务器，并且会导致这些错误，因为您的配置中引用的文件在服务器上不存在。

Answer 2

我在本地收到此错误消息：

警告：无法打开 "\xampp\php\extras\browscap.ini" 进行读取 第0行未知

通过更改php.ini文件的这一行：

browscap="\xampp\php\extras\browscap.ini"

到这里：

browscap="C:\xampp\php\extras\browscap.ini"

错误消失了。

Answer 3

有时候这里的人并不像他们应该的那样......

无论出于何种原因，您的 php.ini 配置错误。

需要注意的是，所有这些丢失的文件实际上都是 Linux 上的 Windows 文件 (*.dll)，它们很可能是 *.so 文件。我假设您在 Linux 服务器上托管。

首先找到你的 php.ini 文件。如果你有通过 SSH 的命令行访问，你可以尝试运行：

php --ini

如果你不做一个简单的脚本，就叫它 test.php 像这样：

<?php
phpinfo();
?>

上传文件并运行它，类似于：

http://www.yoursite.com/test.php

提供的信息中包括 php.ini 的路径

找到它后，一种选择是编辑它并注释掉所有这些扩展名，方法是添加一个“;”排在队伍前面。

另一个选项是检查 *.so 文件是否存在。在 /usr/lib/php 下查找它们。如果它们存在，请编辑您的 php.ini 文件以使所有这些扩展名都以 .so 而不是 .dll 结尾

最后，如果它们不存在，您可以使用 apt-get 或 yum 安装它们。一个例子：

sudo apt-get install php-mbstring
