我使用这里的脚本来生成我的站点地图。

我可以用浏览器调用它，http://www.example.com/sitemap.php?update=pages它工作正常。

我需要将它称为 shell 脚本，以便我可以使用 Windows 任务调度程序自动执行它。但是需要更改脚本才能获取变量?update=pages。但我无法正确更改它。

任何人都可以帮助我，以便我可以从命令行执行脚本

...\php C:\path\to\script\sitemap.php update=pages. 我也可以将变量硬编码到脚本中，因为无论如何我都不会更改它们。

define("BASE_URL", "http://www.example.com/");
define ('BASE_URI', $_SERVER['DOCUMENT_ROOT'] . '/');

我可以安装wget（它也可用于 Windows），然后在任务调度程序脚本中通过 localhost 调用 url：

wget.exe "http://localhost/path/to/script.php?pages=test"

这样你就不必重写 php 脚本了。

否则，如果脚本仅用于 shell，则通过命令行传递变量：

php yourscript.php variable1 variable2 ...

在 php 脚本中，您可以使用以下变量访问这些$argv变量：

$variable1 = $argv[1];
$variable2 = $argv[2];

看看：

如何使用 Shell 将 GET 变量传递给 php 文件？

已经回答了同样的问题:)。
