How to execute PHP script while reading javascript?

[toplisek]

I have to set javascript and execute some small PHP script on another server. How to do this actually in the correct way? Are there any obstacles to do this. I assume Javascript will be enabled.

If js is not enabled it will need to degrade gracefully and provide valid output or suitable error message.

If js is enabled how to do it?

Depends on what you need to do with reply from php script. If you are not interested in reply. then using small scripts url as source of hidden iframe will suffice(no js required).

Otherwise as server is probably on different domain then containing page, Ajax with jsonp or similar needed.
