when we run the program the logic that is defined inside PHP script, $_POST[ ] is used to collect the values from a form. it store the value in variables ($x,$y).

But we want to show the sum inside the textbox. for this we define textbox inside the “echo” statement with (value=”$sum”).

We create form using HTML script with (method=”post”) and action=”output.php”.
We define Five fields inside the HTML form.

First for name,Second for Email_id, Third for Password,Fourth for Mobile No,and Fifth for address.
A button is used to display data on next page after click on this button.

inside the (output.php) page we create same form format. But value attribute of every <input> type tag is used to declare the PHP script inside the value with $_POST[ ] . $_POST[ ] is define with name of a field like. $_POST[‘name’], $_POST[’email’].

As we run this program the dada that is Entered in First page will dispaly as it is data on Second(output.php) page.
