How to fix PHP Warning: PHP Startup: Unable to load dynamic library 'ext\\php_curl.dll'?
提问by Jaylen
I currently have PHP 5.5.12 and Apache 2.4 installed on Windows Server 2008 R2. Everything is running perfectly with no issue/warnings.
我目前在 Windows Server 2008 R2 上安装了 PHP 5.5.12 和 Apache 2.4。一切都运行完美，没有问题/警告。
What I have done is copied the same Apache file/configuration to another server. I copied the C:\PHPdirectory and then the C:\Apache24directory and pasted them into the new server.
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，然后复制了目录并将C:\Apache24它们粘贴到新服务器中。
Then I installed the Apache with one change (ie httpd -k install.) I changed the port number from 80 to 8877. The Apache is working with no issue and it is running on the 8877 port. I can also open the default page by going to SERVER_IP_ADDRESS:8877 and it works.
然后我通过一个更改（即httpd -k install。）安装了 Apache 。我将端口号从 80 更改为 8877。Apache 工作没有问题，它在 8877 端口上运行。我也可以通过转到 SERVER_IP_ADDRESS:8877 打开默认页面并且它可以工作。
But, PHP is not working as it should. In the error.log file from the Apache server I get the warning listed below
但是，PHP 无法正常工作。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_mysqli.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_openssl.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_mysql.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_sqlsrv_55_ts.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
I can't seem to figure out why I get this error? All the .dll files that the warning is stating "The specified module could not be found" do exists in the C:\PHP\ext directoryphp
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 文件都存在于 C:\PHP\ext 目录中

当我尝试访问该网站时出现此错误
Fatal error: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND'
致命错误：未定义的类常量 'MYSQL_ATTR_INIT_COMMAND'
which is because the extensions are not loaded.
这是因为未加载扩展。
I am assuming that the configuration are correct since the same configuration are working on a different server.
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。

As Darrencommented, Apache don't understand php.inirelative paths in Windows.
正如Darren评论的那样，Apache 不理解php.iniWindows 中的相对路径。
In PHP manual we have an How-to install Apache 2.x on Microsoft Windows. One of the commentssuggests using absolute paths.
在 PHP 手册中，我们有一个 How-to install Apache 2.x on Microsoft Windows。其中一条评论建议使用绝对路径。
So, try changing the relative paths in your php.inito absolute paths.
因此，尝试将您的相对路径更改php.ini为绝对路径。

in this perticular case, the php.ini was: extension_dir = "C:/php"
在这种特殊情况下，php.ini 是： extension_dir = "C:/php"
the dll is put in two places C:\php and C:\php\ext
dll 放在两个地方 C:\php 和 C:\php\ext
IS it possible that there is and "error" in the error log entry ? I.e. that the .dll IS found (as a file) but not of the right format, or something like that ??
错误日志条目中是否可能存在“错误”？即找到了 .dll（作为文件）但格式不正确，或者类似的东西？？
