Scripts can be written in any of a number of server-side scripting languages that are available (see below). Server-side scripting is distinguished ...
Simply printing (echoing) user input to the browser without checking it first is something that should be avoided in secure forms processors: if a user entered the JavaScript code < script > alert (1)</ script > into the firstname field, the browser would execute the script on the form_handler.php page, just as if it had been coded by the ...
