如何修复PHP警告：PHP启动：无法加载动态库“ext\\php_curl.dll”？
我目前在Windows Server 2008 R2上安装了PHP 5.5.12和Apache 2.4。一切都运行良好，没有问题/警告。
我所做的是将相同的Apache文件/配置复制到另一台服务器。我复制了目录，然后复制了目录，并将它们粘贴到新服务器中。C:\PHPC:\Apache24
然后我安装了Apache，只有一个更改（即.我将端口号从80更改为8877。Apache正在正常工作，它在8877端口上运行。我也可以通过转到SERVER_IP_ADDRESS：8877打开默认页面，它可以正常工作。httpd -k install
但是，PHP并没有像它应该的那样工作。在错误中.log来自Apache服务器的文件，我得到下面列出的警告
PHP Warning: PHP Startup: Unable to load dynamic library 'ext\\php_curl.dll' - The specified module could not be found.\r\n in Unknown on line 0

我似乎无法弄清楚为什么我会收到此错误？警告指出“找不到指定的模块”的所有.dll文件都存在于 C：\PHP\ext 目录php 中
PHP 扩展位于
C:\php\ext
在文件php内部.ini我有这个变量
extension_dir = "ext"
这里是 ext 文件夹的目录列表

当我尝试访问网站时，我收到此错误
致命错误：未定义的类常量“MYSQL_ATTR_INIT_COMMAND”
这是因为未加载扩展。
我假设配置是正确的，因为相同的配置在不同的服务器上工作。
如何解决此 PHP 启动问题？
