我刚刚安装了 Ubuntu Unity (23.10) 操作系统，并在其中安装了 PHP。
现在我想从终端运行一个 PHP 文件，但它不执行它，而只是打印其内容。（该 PHP 文件来自GitHub 仓库，不是我的。）
打印“Hello world”的简单文件就可以正常工作。
没有错误。

退出代码也是 0。
有什么想法/提示吗？
答案1
该文件用于<?启动 PHP 代码。它应该使用<?php。
使用 bare<?需要short_open_tags启用 PHP 选项（通过 php.ini 或类似文件）。我不建议这样做 - 它可能导致与 XML 文件（用于<?xml其标题）发生冲突，而且实际上并不能节省太多的输入。
即使该项目不是您的，它似乎也是一个足够小的项目，将其拥有的两个 PHP 文件<?的打开标签更改为 会更简单<?php（嗯，一个，因为另一个已经有完整的打开标签）。
