Question

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。

所有库都在 php.ini 文件上打开。 我已经检查了所有这些。 我想知道为什么命令行会尝试以不正确的路径运行库，例如

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

它应该像

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

？

Answer 1

打开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"

在 Windows 上，指向普通硬盘驱动器上某物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。

Answer 2

在 php.ini 中调整以下值：

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

Answer 3

如果扩展目录位于同一文件夹中，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）。

例子：

extension_dir = "ext"

其中ext是您的扩展目录。

Answer 4

检查错误中的 dll / 库路径并确保它是正确的。 将 /php.ini-> extension_dir 更新到正确的路径可以解决我的问题。

Answer 5

我有 7.4 php 版本。 我通过删除取消注释以下行来解决这个问题； 在 php.ini 文件中。

extension_dir = "ext"

请注意，最初，如果您没有 php.ini 文件，您应该首先复制并粘贴 php.ini-development 文件并将其重命名为 php.ini。
