在 Windows 中运行 PHP：如何解决“PHP 启动：无法加载动态库”问题？

Running PHP in Windows: how to fix "PHP Startup: Unable to load dynamic library" issues?

提问by Don Korleone

I have determined path to php folder and trying to run some php file and getting this message from command line.

我已经确定了 php 文件夹的路径并尝试运行一些 php 文件并从命令行获取此消息。

All libraries are open on php.ini file. I have checked them all. I am wondering why command line tries to run library in incorrect path like

所有库都在 php.ini 文件中打开。我都检查过了。我想知道为什么命令行尝试在不正确的路径中运行库，例如

'/usr/local/php5/ext\php_xsl.dll'

Does it should be like

是不是应该像

'/usr/local/php5/ext/php_xsl.dll'

?

?

Open your php.inifileand set the following setting to a Windowsfile path:

打开您的php.ini文件并将以下设置设置为Windows文件路径：

extension_dir = "X:/path/to/your/php/ext"

On Windows, paths that point to something on a normal hard drive have to start with a letter and then a colon, like "C:". Paths that startwith a forward slash, /, are Unix-like paths, and will not work on Windows.

在 Windows 上，指向普通硬盘驱动器上某些内容的路径必须以字母开头，然后是冒号，例如“ C:”。以正斜杠 ,开头的路径/是类 Unix 路径，在 Windows 上不起作用。

Adjust the following value in php.ini:

在 php.ini 中调整以下值：

; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:\path to extension directory"

You can also specify the extensions directory without using the full path if it's in the same folder, at least in PHP 7.2.5 (have not tested other versions).

如果扩展目录在同一文件夹中，您也可以指定扩展目录而不使用完整路径，至少在 PHP 7.2.5 中（尚未测试其他版本）。

Example:

例子：

extension_dir = "ext"

extension_dir = "ext"

Where extis your extensions directory.

ext你的扩展目录在哪里。
