modifying HTML cells in PHP

[blaster_master]

How is it possible to refer to a specific HTML table cell in PHP? Example:

Assume there is a simple HTML table with m rows and n columns. Outside this table there is a link which when pressed should change the color of the 2 - 4 cell (row 2, column 4) from #A to #B. If not possible in PHP, how can one do it in HTML? (I'd just echo the HTML solution in PHP)

Any help is appreciated.

You wouldn't want to do it in PHP, because PHP runs on the server and wouldn't know if anyone had clicked anything until it was asked to deliver a new page, and I suspect you don't want to reload the entire page just so that you can change the colour of a table cell. You can't do it in HTML because HTML isn't a programming language and so can't do anything.

You could do it in Javascript: give the relevant <td> element an id attribute, and then Javascript can locate the cell with getElementById('whateveryoucalledit');
