php - 如何修复 PHP 警告 : PHP Startup: Unable to load dynamic library 'ext\\php_curl.dll' ?

Question

我目前在 Windows Server 2008 R2 上安装了 PHP 5.5.12 和 Apache 2.4。一切运行良好，没有任何问题/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 C:\PHP 目录，然后复制了 C:\Apache24 目录并将它们粘贴到新服务器中。

然后我安装了 Apache 并进行了一次更改(即 httpd -k install。我将端口号从 80 更改为 8877。Apache 工作正常，它在 8877 上运行港口。我也可以通过转到 SERVER_IP_ADDRESS:8877 打开默认页面，它可以工作。

但是，PHP 不能正常工作。在 Apache 服务器的 error.log 文件中，我收到下面列出的警告

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
PHP Warning:  PHP Startup: Unable to load dynamic library 'ext\\php_ldap.dll' - The specified module could not be found.\r\n in Unknown on line 0

PHP Warning:  PHP Startup: Unable to load dynamic library 'ext\\php_pdo_sqlsrv_55_ts.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会出现此错误？警告指出“找不到指定的模块”的所有 .dll 文件确实存在于 C:\PHP\ext 目录php

PHP 扩展位于

C:\php\ext

在 php.ini 文件中我有这个变量

extension_dir = "ext"

这是 ext 文件夹的目录列表

 Volume in drive C is OS
 Volume Serial Number is C63C-1D75

当我尝试访问该网站时出现此错误

Fatal error: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND'

这是因为扩展没有加载。

我假设配置是正确的，因为相同的配置在不同的服务器上运行。

如何解决这个 PHP 启动问题？

Answer 1

作为 Darren commented , Apache 不理解 php.ini 在 Windows 中的相对路径。

要修复它，请将 php.ini 中的相对路径更改为绝对路径。

extension_dir="C:\full\path\to\php\ext\dir"
