使用变量从php工作到shell工作，改变php脚本

Question

I use a script from here to generate my sitemaps.

I can call it with the browser with http://www.example.com/sitemap.php?update=pages and its working fine.

I need to call it as shell script so that I can automate it with the windows task scheduler. But the script needs to be changed to get the variables ?update=pages. But I don't manage to change it correctly.

Could anybody help me so that I can execute the script from command line with

...\php C:\path\to\script\sitemap.php update=pages. It would also be fine for me to hardcode the variables into the script since I wont change them anyway.

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

Answer 1

I could install wget (it's available for windows as well) and then call the url via localhost in the task scheduler script:

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

This way you wouldn't have to rewrite the php script.

Otherwise, if the script is meant for shell usage only, then pass variables via command line:

php yourscript.php variable1 variable2 ...

In the php script you can than access those variables using the $argv variable:

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