WRITE THE CODE THAT PROCESSES THE DATA ENTERED BY THE USER 1. Open the index.php file for this application and review the code. Note that it doesn't process the data. Instead, it just displays the data on the form. 2. Open the number tester.php file for this application and review the code. Note that the PHP code that displays the Smessage variable uses the nl2br0 function to convert new line characters to tags. 3. Add the code that uses the data that's entered into the text box controls to display a message that's formatted like this: Number 1: 78 Number 2: -105.33 Number 3: 0.0049 Number 2 ceiling: -105 Number 2 floor -106 Number 3 rounded: 0.005 Min: -105.33 Max: 78 Random: 86 When formatting this message, use escape sequences to insert new line characters. 4. Make sure the user enters all three numbers and that these numbers are valid. 5. Make sure the rounded number is rounded to 3 decimal places. 6. Make sure the random number is a number between 1 and 100 7. Test the application to make sure it works correctly with the default values and also with other values
