在 Windows 中運行 PHP：如何解決“PHP 啟動：無法加載動態庫”問題？

Question

我已經確定了 php 文件夾的路徑並嘗試運行一些 php 文件並從命令行獲取此消息。

所有庫都在 php.ini 文件上打開。 我已經檢查了所有這些。 我想知道為什么命令行會嘗試以不正確的路徑運行庫，例如

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

它應該像

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

？

Answer 1

打開php.ini文件並將以下設置設置為Windows文件路徑：

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

在 Windows 上，指向普通硬盤驅動器上某物的路徑必須以字母開頭，然后是冒號，例如“ C: ”​​。 以正斜杠/開頭的路徑是類 Unix 路徑，在 Windows 上不起作用。

Answer 2

在 php.ini 中調整以下值：

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

Answer 3

如果擴展目錄位於同一文件夾中，您也可以指定擴展目錄而不使用完整路徑，至少在 PHP 7.2.5 中（尚未測試其他版本）。

例子：

extension_dir = "ext"

其中ext是您的擴展目錄。

Answer 4

檢查錯誤中的 dll / 庫路徑並確保它是正確的。 將 /php.ini-> extension_dir 更新到正確的路徑可以解決我的問題。

Answer 5

我有 7.4 php 版本。 我通過刪除取消注釋以下行來解決這個問題； 在 php.ini 文件中。

extension_dir = "ext"

請注意，最初，如果您沒有 php.ini 文件，您應該首先復制並粘貼 php.ini-development 文件並將其重命名為 php.ini。
