Let's say i have a webserver from whatever hosting website service that supports php, and i want my arduino to send a number for example and for it to be displayed in the page, how do i do this?
I know there are some tutorials, but most of them barely explain anything and i want to know what i'm doing, and i prefer to know how to send a simple var and then go from there. So is there any basic sketch and php script ?
Also, where can i find documentation for these type of problems?
Thanks in advance
edit: forgot to mention i have arduino uno + ethernet shield
