Hey, not sure if this is possible with PHP, but I thought I'd ask anyway. Is it possible to update values on an html page based on values being typed into an input box? For example. My table has three columns. Column 1 has an integer in it. Column two is a blank text input box. I would like column three to dynamically show the total of column 1 plus column 2. So whatever number you put in the box in column 2 would be automatically added to the number in column one, and show the total in column 3, without hitting a button or anything. Is this possible with html and php? If not, what would be the language best suited to accomplish this?
