Most PHP installations do an auto addslashes to $_GET input, so if you echo them to the page or send them to somewhere that won't strip or need the slashes, you will want to stripslashes the output.

This is data (arguments) passed the the apge being called. In PHP you can access these values via the predefined $_GET array. In the example you gave, $_GET['id'] would be set to 202. you can have more than one, they are generally given in the format of ?name=value&name=value&name=value

Be sure that you always validate/check the values before just using them in a script. If you go to use any values in things such as URLs, Filenames, SQL statements, etc, make sure that you escape out the values with something like addslashes().
