我无法在此站点上找到此问题。当我加载我的页面时，我收到以下错误
Call to undefined function mysql_query()
所以我检查了我的phpinfo()文件，我根本找不到 mysql 扩展或任何扩展。所以我进入我的 php ini 文件并取消注释扩展
extension=php_pdo_mssql.dll
extension=php_pdo_mysql.dll
我重新启动了我的 apache 服务器和 mysql，但没有任何改变，扩展名也没有被识别。我有 mysql 服务器正在运行，我有 apache 与 php 一起运行，但我很难加载扩展。所以我检查了我的扩展目录（我phpinfo()指定的目录，那里什么都没有。）MacPorts 安装了除了我的扩展之外的所有东西。有没有搞错 ？？还有什么我想念的吗？

我正在使用 Mac 并检查上面的设置。我也安装了 php_mysql.dll 文件
extension=php_mysql.dll
extension=php_mysqli.dll
这是我的phpinfo()页面
我的页面上出现了 3 次 mysql 一词。
编辑
好的，我有一个屏幕截图，显示了扩展目录的位置，但是当我去那里时，我没有看到任何扩展。macports安装会损坏吗？
