我正在尝试查看是否安装了php。我尝试运行php -v但我将其作为输出。有什么想法是错误的吗？
(33)$ php -V

我不知道你的 Linux 风格，但这里有一个关于它是如何工作的快速概述，至少在 RedHat 下是这样。
如果您编译自己的 PHP，您可能也会编译这些扩展，然后将它们加载到 php.ini 中。但是在包（如php-mysql）中，你不能这样做。如此多的风格将设置/etc/php.d，您将找到所有包含对编译（.so）文件的引用的ini文件（即xdebug.ini）。这些文件在运行时加载，就像 Apache 在运行时加载所有 *.conf 文件一样。
这里有几种可能性
- 您的 PHP 配置错误，正在查看错误的目录。
- 您没有从命令行访问该目录的权限（如果 PHP 在 Web 服务器下工作，则可能是这种情况）
- 其他东西（即 selinux）导致问题
因此，请查看您是否可以访问/usr/lib64/php/modules并确保 .so 文件在那里。如果没有，请弄清楚他们住在哪里。该指令称为 config-file-scan-dir
