我正在尝试将批处理嵌入到 php 中，但它没有执行

Question

So, I'm trying to setup a batch executable inside a website (php in this case), so it would download certain file directly to desired directory, without need for user to interact with it. Basically the plan is if there was a website with mods/in-game builds/worlds for a game, you'd want to download them directly into AppData, and not bother with moving it from Downloads manually. I am using Xampp localhost to test run it (and I did run it as admin).

I searched up online to find how to embed batch inside php, and got to this:

<?php
    exec("cd %AppData% && curl <LINK> -o <NAME>.<FILE_SUFFIX>");
?>

I tried with 'system' instead of 'exec', adding 'cmd /c' in front of the command as well, but not working either

I tried a different approach after that, just to test

<?php
    exec("start batch.bat");
?>

with this code

@echo
cd %AppData% 
curl <LINK> -o <NAME>.<FILE_SUFFIX>
pause

Which resulted in

'curl' is not recognized as an internal or external command, operable program or batch file.

I also tried absolute path instead of relative, but no positive result either.

Now I don't know what else to try and what could be causing this. If there is another viable option to achieve what I've stated above, please do let me know as well.

So here's the working code I am using now

<?php
    exec("bitsadmin /transfer myDownloadJob /download /priority high <LINK> <TARGET_LOCATION_FILE>");
?>

I still don't know why the curl didn't work, but as bitsadmin is native windows command, it's better anyway. Thanks to everyone who helped!
