Write a PHP script using regular expressions for validating the data submitted by a form with two text fields, simplified IP address and date as shown in the nine screenshots of my browser window. The required format for the IP address containing digits separated by dot character '.' is: ddd.ddd.d.dd, while the required date format is mm/dd/yyyy. The script will accept the inputs from textboxes. Hint: Along with input validation it is also important that any data the user has already entered remains on the form. This means that the form returned when the input does not pass the validation should remember the entered values (it should be sticky). My PHP Forms PowerPoint slides (p. 32-55) show how to do that.
